  • [Title] Management of hepatic angiomyolipoma.
  • Preoperative diagnosis of hepatic angiomyolipoma is difficult, and the treatment for it remains controversial.
  • The aim of this study is to review our experience in the treatment of hepatic angiomyolipoma and to propose a treatment strategy for this disease.
  • We retrospectively collected the clinical, imaging, and pathological features of patients with hepatic angiomyolipoma.
  • During a period of 9 years, 10 patients with hepatic angiomyolipoma were treated at our hospital.
  • We propose all symptomatic patients should receive surgical resection for hepatic angiomyolipoma.
  • (1) tumor size smaller than 5 cm, (2) angiomyolipoma proved through fine needle aspiration biopsy, (3) patients with good compliance, and (4) not a hepatitis virus carrier.

  • Frequently found in kidney, angiomyolipoma is a rare mesenchymal tumor when diagnosed in the liver and usually benign composed of proliferative blood vessels, fatty tissue and smooth muscle.
  • Final anatomopathologic examination revealed an epithelioïd hepatic angiomyolipoma with signs of malignant behaviour as vascular and lymphatics embolus and invaded left portal vein thrombosis.
  • A review of the literature found only two cases of malignant hepatic angiomyolipoma with fatal issue, however, their incidence must be underrated because of their scarcity and the difficulty of their diagnosis, which needs immunohistochemical confirmation with HMB 45 in particularly.
  • Advances in imaging and anatomopathology in particular with the concept of PEComa (Perivascular-Epithelioïd Cell) as the unifying feature should lead to the recognition of the various variant patterns and cell types.
  • The latter which are important for a correct diagnosis, in order to obtain reliable data about frequency, possible malignant behaviour and therefore consensus management for hepatic angiomyolipoma.

  • [Title] Hepatic angiomyolipoma.
  • Hepatic angiomyolipoma is a rare, benign, hepatic mesenchymal neoplasm found in both males and females, and most commonly in adult females.
  • Angiomyolipoma occurs most commonly in the kidneys.
  • The liver represents the second most frequent site of involvement.
  • Hepatic angiomyolipomas are composed of varying amounts of smooth muscle cells, adipose tissue, and vessels.
  • The smooth muscle cell component is the most specific to the diagnosis.
  • The differential diagnosis includes hepatocellular carcinoma, hepatic adenoma, leiomyoma, hepatoblastoma, melanoma, and gastrointestinal stromal tumor.
  • The immunohistochemical staining pattern differentiates this lesion from other malignant and benign liver lesions.
  • If the diagnosis of hepatic angiomyolipoma has been made, it can be followed conservatively or surgically resected.

  • Lipoma of the liver is extremely rare.
  • This report presents a case of lipoma of the liver mimicking angiomyolipoma.
  • Radiological examinations (computed tomography, ultrasonography, magnetic resonance imaging) showed a well-defined mass, which was finally diagnosed to be located in the left part of the caudate lobe of the liver, containing two spotty enhanced nodules within the tumor.
  • These were diagnosed to be either lipoma or angiomyolipoma of the liver.
  • The cut surface of the specimen showed an encapsulated, homogeneous, yellowish tumor consisting of mature adipose tissue, which was diagnosed as lipoma of the liver.
  • Therefore, the final diagnosis was lipoma of the liver, which is an extremely rare benign liver tumor.

  • [Title] Diagnostic analysis of hepatic angiomyolipoma.
  • BACKGROUND: Hepatic angiomyolipoma (HAML) is a rare tumor containing a variable amount of fat, vessels and smooth muscle.
  • RESULTS: A huge heterogeneous hyperecho mass with anecho and hypoecho areas inside was found in the left hepatic lobe on ultrasonography.
  • CT scan showed a huge heterogeneous solid mass in the left lobe of the liver, with a low density and hypervascular area in arterial phase.
  • CONCLUSIONS: Preoperative diagnosis of HAML relies on combination of CT, MRI and ultrasonography.
  • Ultrasound-guided biopsy combined with morphological manifestation and specimen examination for HMB-45 may be helpful in the diagnosis of HAML.

  • BACKGROUND: To evaluate the triple-phase CT findings for the differentiation of fat-deficient angiomyolipoma from hepatocellular carcinoma in non-cirrhotic liver.
  • METHODS: We retrospectively reviewed contrast-enhanced triple-phase CT images of 10 patients with fat-deficient hepatic angiomyolipoma and 28 patients with 29 hepatocellular carcinomas in non-cirrhotic liver proved on histologic examination.
  • The tumoral vessels in the angiomyolipoma were more prominent and ectatic, were distributed both centrally and peripherally, and were seen in smaller tumors than in the hepatocellular carcinoma.
  • CONCLUSIONS: The presence of early draining vein connecting with prominent tumoral vessels and absent tumor capsule were useful CT findings for the differentiation of fat-deficient angiomyolipoma from hepatocellular carcinoma in non-cirrhotic liver.

  • [Title] Invasive growth of hepatic angiomyolipoma; a hitherto unreported ominous histological feature.
  • AIMS: Although histological features of hepatic angiomyolipoma (AML) are highly variable, true malignant change is extremely rare.
  • The aim was to review the histological features of invasive growth and clinical outcomes in 39 cases of hepatic AML.
  • METHODS AND RESULTS: An invasive growth pattern into surrounding hepatic parenchyma, portal triads and/or around hepatic veins was found in 24 of 39 tumours (62%).
  • One variant showed tumour cells replacing hepatocytes within the liver cell cords.
  • CONCLUSIONS: A previously unrecognized histological feature of an invasive growth pattern, which suggests malignancy and might promote an erroneous diagnosis, was frequently found in hepatic AMLs.
  • However, among about 180 reported hepatic AMLs, including the present cases, only one hepatic AML with distant metastasis has been reported to date and nearly all hepatic AMLs behave in a benign fashion.

  • We report two patients with rare hepatic angiomyolipoma and demonstrate the special tumour haemodynamics with contrast-enhanced harmonic ultrasound.
  • This reliably identified the efferent vessel of the hepatic angiomyolipoma to be the hepatic vein in both cases, which corresponded well with that seen on conventional angiography and CT angiography.
  • This haemodynamic finding may be an important characteristic of hepatic angiomyolipoma, and facilitate the differential diagnosis from other benign and malignant hepatic tumours.

  • [Title] Hepatic angiomyolipoma: dynamic computed tomography features and clinical correlation.
  • AIM: To study the dynamic computed tomography (CT) features of hepatic angiomyolipoma (AML) in patients with or without tuberous sclerosis complex (TSC).
  • METHODS: The clinical information, CT findings and histopathological results of hepatic AML were analyzed retrospectively in 10 patients.
  • RESULTS: Hepatic AML was prone to occur in female patients (7/10), and most of the patients (8/10) had no specific symptoms.
  • All tumors presented as well-defined, unenveloped nodules in the liver.
  • Six patients with sporadic hepatic AML had a solitary hepatic nodule with a definite fat component.
  • Non-fat components of the hepatic lesions were enhanced earlier and persistently.
  • In four patients with hepatic AML and TSC, most of the nodules were within the peripheral liver.
  • CONCLUSION: Imaging features of hepatic AML are characteristic.
  • Correct diagnosis preoperatively can be made in combination with clinical features.

  • [Title] Hepatic angiomyolipoma: a clinical experience in diagnosis and treatment.
  • BACKGROUND: Hepatic angiomyolipoma is a rare mesenchyme-derived neoplasm often misdiagnosed as hepatocellular carcinoma, and the treatment for it remains controversial.
  • AIMS: To develop the optimal preoperative diagnoses means and treatment modalities of hepatic angiomyolipoma.
  • METHODS: Retrospective analysis of the clinical features, treatment, and prognostic data of 17 hepatic AML patients admitted to Chinese People's Liberation Army Generation Hospital between 1996 and 2006.
  • RESULTS: Most hepatic angiomyolipoma were solitary.
  • All of the 17 patients finally received various liver resection procedures, and postoperative mortality and morbidity was 0 and 12% (2/17).
  • CONCLUSIONS: Hepatic angiomyolipoma should be suspected in liver tumor patients with normal α-fetoprotein levels and no concomitant hepatitis.
  • Small hepatic AML proved through pathologic examination (<5 cm) may be managed by observation with close follow-up, but surgery is indicated in patients suffering from large tumors or significantly larger tumors during follow-up.

  • Malignant angiomyolipoma (AML) of the liver is rare.
  • A 30-year-old man had developed giant hepatic masses.
  • Microscopically, the periphery of the tumor showed components of classic hepatic AML, but the central region contained atypical epithelioid components with extremely pleomorphic and hyperchromatic nuclei with frequent mitotic figures.
  • Markedly atypical epithelioid cells with vascular invasion, distant metastasis, and fatal outcome were interpreted as malignant characteristics of hepatic AML.
  • It is suggested that large tumor size, pleomorphic nuclei with high proliferation activity, and P53 immunoreactivity may predict the existence of malignant transformation of hepatic AML.

  • [Title] Hepatic angiomyolipoma with trace amounts of fat: a case report and literature review.
  • Hepatic angiomyolipoma (AML), a rare benign mesenchymal tumour, is characterised by the presence of mature adipose tissue, smooth-muscle cells and thick-walled blood vessels.
  • Increasing attention to hepatic AMLs has led to the discovery that sufficient proportions of fat often allow for definite diagnoses preoperatively.
  • One case of hepatic AML is reported, where the amount of fat was <1%.
  • Abdominal ultrasonography showed a hypoechoic mass measuring 5 cm in diameter and without an obvious capsule in the left lobe of the liver.
  • A dynamic computed tomography scan showed a well-defined and slightly enhanced mass in the medial segment of the left lobe of the liver.
  • Microscopically, the amount of fat was too low to establish a diagnosis of hepatic AML.
  • However, positive homatropine methylbromide 45 immunoreactivity of the smooth-muscle cells seemed to assist in arriving at the diagnosis.

  • [Title] Massive hepatic angiomyolipoma in a young woman with tuberous sclerosis complex: significant clinical improvement during tamoxifen treatment.
  • BACKGROUND/AIMS: Isolated liver angiomyolipomas (AMLs) occur in about 40% of TSC patients.
  • Since AMLs express estrogen and progesteron receptors we suggest the possible benefits of tamoxifen for the treatment of liver AMLs.
  • METHODS: We report the case of a 26-year-old female affected by tuberous sclerosis (TSC2) with cerebral, renal and hepatic involvement admitted to the Liver Unit for severe malnutrition, anorexia and abdominal pain.
  • MRI showed a grossly enlarged liver, causing severe gastric compression.
  • The liver was entirely filled with multiple nodular lesions of different sizes.
  • Liver biopsy showed tumoral tissue with microscopic and ultrastructural features of angiomyolipoma.
  • All liver function tests were repeatedly normal.
  • CONCLUSIONS: This is to our knowledge the first report in which tamoxifen has been successfully used in a TSC patient with multiple liver angiomyolipomas.

  • Angiomyolipoma (AML) is a uncommon benign neoplasm of the liver with cyto- and histologic features similar to the more commonly encountered renal AML.
  • Because most liver lesions are first evaluated by fine-needle aspiration biopsy (FNAB), it is important to distinguish this variant of AML from more common hepatic neoplasms such as hepatocellular carcinoma (HCC) or metastatic tumors.
  • Rare reports of epithelioid AML of the liver diagnosed by FNAB are in the literature.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Hepatic angiomyolipoma and hepatic stellate cells share a similar gene expression profile.
  • BACKGROUND AND AIMS: Angiomyolipomas (AMLs) of the liver are rare neoplasms composed of large epithelioid cells with intermixed fat and blood vessels.
  • Hepatic AMLs have no clear normal-cell counterpart in the liver.
  • METHODS: To further explore the similarities between hepatic AMLs and stellate cells, gene expression of a hepatic AML was studied by cDNA microarray.
  • Hepatic stellate cells can be quiescent, activated, or have a myofibroblastic phenotype depending on their state of activation.
  • RESULTS: Overexpression of known markers of activated stellate cells including transforming growth factor beta (TGF- beta ), smooth muscle actin, and collagen was found in the hepatic AML.
  • CONCLUSIONS: Hepatic AMLs share a similar gene expression profile and may differentiate toward activated stellate cells.

  • Hepatic angiomyolipoma (AML) is known as a rare benign tumor with invasive growth.
  • Here in this article, we report a case of hepatic AML which showed a size increase of 175% in 1 year, and portal vein thrombosis detected by angiography.
  • During a follow up of 3 years after a curative hepatic lobectomy, no metastasis or recurrence was seen.
  • Therefore, in this paper, we recommend surgical treatment of hepatic AML in which there is a strong suspicion of portal vein thrombosis.

  • Unlike the common development of renal angiomyolipoma, hepatic angiomyolipoma rarely occur in patients with TSC.
  • We report here a patient with hepatic angiomyolipomas and concurrent hepatocellular carcinoma in TSC.
  • In this patient, multiple hepatic angiomyolipomas were diagnosed with recognition of their fat components and typical clinical settings.
  • Hepatocellular carcinoma in the left liver lobe was definitely diagnosed by US guided biopsy.
  • In such clinical settings, fat containing lesions in liver can be reasonably treated as angiomyolipomas, but non fat containing lesions must be differentiated from hepatocellular carcinoma, imaging guided biopsy can be adopted to confirm the diagnosis.

  • [Title] Imaging features of hepatic angiomyolipomas on real-time contrast-enhanced ultrasound.
  • The aim of this study was to evaluate the imaging features of hepatic angiomyolipoma (AML) on contrast-enhanced ultrasound (CEUS).
  • The imaging features of 12 pathologically proven hepatic AML lesions in 10 patients who had undergone baseline ultrasound (BUS) and CEUS examinations were evaluated retrospectively.
  • Before pathological examination with BUS, only 3 (25%) lesions were correctly diagnosed as hepatic AML.
  • Conversely, on CEUS, correct diagnoses were made for 66.8% (8/12) of hepatic AMLs.
  • Therefore, arterial hyperenhancement and subsequent sustained enhancement on CEUS were found in the majority of hepatic AMLs.
  • The combination of BUS and CEUS leads to the correct diagnosis in the majority of hepatic AMLs, and is higher than the success rate achieved by BUS alone.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] The differential broadens. EUS FNA appearance and cytological findings of pancreatic angiomyolipoma.
  • CONTEXT: Angiomyolipoma is a rare tumor characterized histologically by a mixture of spindle cells, adipose tissue, epithelioid cells, and vascular tissue.
  • It usually involves the kidney followed by the liver whereby the majority of affected patients are female, and many cases arise in the setting of tuberous sclerosis.
  • CASE REPORT: We report a case of a 33-year-old female with an asymptomatic incidental right renal mass suggestive of an angiomyolipoma in conjunction with numerous pancreatic masses.
  • CONCLUSIONS: The utility of EUS in the differential diagnosis of pancreatic tumors is well established.
  • This is the first known reported EUS detection and FNA confirmation of angiomyolipoma metastatic to the pancreas and should now be added to the already broad differential of metastatic pancreatic tumors.

  • [Title] Acute abdomen as an unusual presentation of hepatic PEComa. A case report.
  • They are rare mesenchymal tumors and include subtypes with distinct clinical features: angiomyolipoma, lymphangioleiomyomatosis, and clear cell "sugar" tumors of the lung, pancreas and uterus.
  • These hepatic PEComas, different from angiomyolipoma of the liver, pose a clinical, radiological and morphological diagnostic challenge.
  • Liver laboratory tests showed slight elevation of AST, ALT and gamma-GT.
  • The radiological images showed a hemorrhagic mass with some bizarre features in left hepatic lobe, immediately adjacent to the ligamentum teres and falciform ligament.
  • The patient underwent a left hepatic lobectomy.
  • The diagnosis of CCMT was based on histological and immunohistochemical staining.
  • We recommend that all unusual carcinomas and mesenchymal tumors of the liver should be tested for HMB-45: when positive, there is a high likelihood of PEComa.

  • Perivascular epithelioid cell tumours (PEComas) are a family of tumours including classic angiomyolipoma, lymphangioleiomyomatosis, and clear epithelioid cell tumours reported under a variety of names such as epithelioid angiomyolipoma, pulmonary and extrapulmonary clear cell sugar tumour, and PEComa.
  • We collected ten sporadic and two tuberous sclerosis complex-associated PEComas, as well as 14 sporadic classic hepatic and renal angiomyolipomas (AMLs) as controls.
  • The incidence of genetic aberrations was significantly higher in the PEComa group.
  • Only one PEComa showed LOH at the TSC1 locus.
  • Our observations of frequent deletion of TSC2 and the mTOR signalling pathway provide evidence that the oncogenetic lineage of PEComa, as a distinct TSC2-linked neoplasm, is similar to that of angiomyolipoma.

  • [Title] Estrogen enhances whereas tamoxifen retards development of Tsc mouse liver hemangioma: a tumor related to renal angiomyolipoma and pulmonary lymphangioleiomyomatosis.
  • Pulmonary lymphangioleiomyomatosis and abdominal angiomyolipoma are related lesions for which there is no authentic animal model.
  • Tsc1+/- and Tsc2+/- mice frequently develop liver hemangioma.
  • We found that the Tsc mouse liver hemangioma are composed predominantly of endothelial cells but with a smooth muscle component, and express HMB45 antigen, estrogen receptor, and progesterone receptor, similar to lymphangioleiomyomatosis and angiomyolipoma.
  • Estrogen treatment significantly accelerated the development of liver hemangioma in Tsc1+/- female mice, with 91% having liver hemangioma and 55% having severe lesions by 7 months of age.
  • Similarly, an increased frequency and severity of liver hemangiomas was seen in Tsc1+/- males treated with estrogen.
  • These mouse model observations indicate the importance of estrogen signaling in vivo for the growth of tuberous sclerosis lesions, suggesting the possible benefits of tamoxifen therapy for the treatment of angiomyolipoma and lymphangioleiomyomatosis.

  • Prophylactic embolisation may be considered in some cases, depending on lesion size and patient co-morbidities.We present a case of retroperitoneal bleeding from a renal angiomyolipoma in a patient with known cirrhosis of the liver, which caused acute deterioration of liver function and consequent hepatic encephalopathy.
  • Such functional hepatic decompensation has not previously been reported in this context and we suggest the use of prophylactic embolisation for incidental renal angiomyolipomata, regardless of size, in all patients with chronic liver disease to prevent this potentially life-threatening complication.

  • The left kidney had been surgically resected at the age of 34, and the left renal tumor was pathologically diagnosed as classic angiomyolipoma and epithelioid angiomyolipoma.
  • Metastatic lesions were identified in the right lung, liver, diaphragm, and mesentery.
  • Immunohistochemical examination showed epithelioid angiomyolipoma cells that were focally reactive for HMB-45 and showed diffuse positive staining for Melan-A.
  • This case was proven to be malignant because of the occurrence of distant metastases, and showed that p53 mutations are not always associated with malignant transformation in epithelioid angiomyolipoma.

  • We describe an unusual case of hepatic PEComa arising in a 55-year-old woman with previous history of glioblastoma.
  • Histologically the tumor grew in expansive way, and was composed of clear and eosinophilic epithelioid cels, without vascular or lipomatous component characteristic of angiomyolipoma.
  • The main differential diagnosis of hepatic PEComa includes clear cell variant of liver cell adenoma and hepatocellular carcinoma, metastases of various clear cell carcinomas and metastasis of malignant melanoma.
  • In respect of uncertain biologic potential of PEComa, long term follow up is indicated.

  • [Title] Malignant neoplasm of perivascular epithelioid cells of the liver.
  • Although this group includes entities with distinct clinical features, such as angiomyolipoma, clear cell sugar tumor of the lung, and lymphangioleiomyomatosis, similar tumors have been documented in an increasing diversity of locations.
  • The term PEComa is now generally used in reference to these lesions that are not angiomyolipomas, clear cell sugar tumors, or lymphangioleiomyomatoses.
  • We present a case of hepatic PEComa with benign histologic features, which nonetheless presented with metastases to multiple sites nearly 9 years later.
  • This case represents the second documented malignant PEComa of the liver, as well as the longest follow-up of a surviving patient with a malignant PEComa, emphasizing both the need for criteria that more accurately predict the behavior of PEComas and the necessity of long-term follow-up of patients with PEComas.

MedlinePlus Health Information. consumer health - Liver Cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Podoplanin is a useful diagnostic marker for epithelioid hemangioendothelioma of the liver.
  • However, its expression in non-neoplastic and neoplastic liver tissues has not been well documented.
  • In this study, we examined podoplanin expression in specimens from 10 normal livers and 73 cases of liver tumors: hemangioma (16 cases), epithelioid hemangioendothelioma (9 cases), angiosarcoma (4 cases), angiomyolipoma (7 cases), hepatocellular carcinoma (11 cases), intrahepatic cholangiocarcinoma (11 cases), and metastatic liver cancer (15 cases).
  • We compared levels of podoplanin and other endothelial markers (CD31, CD34, and factor VIII) in liver tumors.
  • In the normal liver, podoplanin was expressed in lymphatic endothelium, nerve fibers, and mesothelium in the hepatic capsule, but not observed in any cells within hepatic lobules.
  • Among liver tumors, podoplanin was specifically expressed in seven of nine cases (78%) of epithelioid hemangioendothelioma but not in other hepatic tumors.
  • The expression of CD31, CD34, and factor VIII was observed in endothelial cells in all cases of hemangioma, epithelioid hemangioendothelioma, angiosarcoma, and angiomyolipoma with one exception, a case of epithelioid hemangioendothelioma which was without CD31 expression.
  • In conclusion, podoplanin would be useful as a diagnostic marker for epithelioid hemangioendothelioma in liver tumors.

  • [Title] Characterization of focal liver lesions: comparison of pulse-inversion harmonic contrast-enhanced sonography with contrast-enhanced CT.
  • PURPOSE: To compare the efficacy of contrast-enhanced pulse-inversion harmonic sonography for the characterization of focal liver lesions with that of contrast-enhanced helical CT.
  • METHODS: Real-time contrast-enhanced sonography (CEUS) using Sonovue and contrast-enhanced CT (CECT) were performed on 109 patients with focal liver lesions, including 61 hepatocellular carcinomas, 15 liver metastases, 5 cholangiocellular carcinomas, 12 hemangiomas, 5 regenerative nodules, 3 adenomas, 3 focal nodular hyperplasias, 4 focal necroses, and 1 angiomyolipoma prior to surgery or percutaneous needle biopsy.
  • CONCLUSION: Real-time pulse-inversion harmonic CEUS with Sonovue is comparable with CECT in the characterization of focal liver lesions.

  • [Title] Fat-containing lesions of the liver: radiologic-pathologic correlation.
  • Fat-containing tumors of the liver are a heterogeneous group of tumors with characteristic histologic features, variable biologic profiles, and variable imaging findings.
  • Benign liver lesions that contain fat include focal or geographic fatty change (steatosis), pseudolesions due to postoperative packing material (omentum), adenoma, focal nodular hyperplasia, lipoma, angiomyolipoma, cystic teratoma, hepatic adrenal rest tumor, pseudolipoma of the Glisson capsule, and xanthomatous lesions in Langerhans cell histiocytosis.
  • Malignant liver lesions that can contain fat include hepatocellular carcinoma, primary and metastatic liposarcoma, and hepatic metastases.
  • Identification of fat within a liver lesion can be critical in characterization of the lesion.
  • The imaging characteristics of a lesion coupled with the pattern of intratumoral fatty change are helpful in narrowing the differential diagnosis.

  • OBJECTIVE: Our purpose was to review a broad spectrum of mesenchymal liver tumors in adults and present their cross-sectional imaging characteristics including radiologic-pathologic correlation.
  • CONCLUSION: Cross-sectional imaging findings of mesenchymal liver tumors in adults are varied and some may overlap with others or even with more common malignant epithelial tumors.
  • However, in some cases, their appearances at cross-sectional imaging studies may reflect characteristic abnormalities that suggest a specific diagnosis.
  • Therefore, familiarity with the radiologic findings of mesenchymal liver tumors and understanding their pathological background is important for increasing the accuracy of radiologic diagnosis.

  • [Title] Liver transplantation for multiple angiomyolipomas complicating tuberous sclerosis complex.
  • Tuberous sclerosis complex is a genetic multisystem disorder characterised by widespread hamartomas in several organs, including the brain, heart, skin, eyes, kidney, lung, and liver.
  • Hepatic multiple, bilateral angiomyolipomas are a rare and usually asymptomatic complication in patients with tuberous sclerosis.
  • We report here the case of a patient who needed liver transplantation because of debilitating manifestations and mechanical complications of massive liver involvement by multiple angiomyolipomas (severe malnutrition, anorexia and abdominal pain).
  • Seventeen tumors, from 2 to 16 cm in diameter, were identified at examination of the liver explant.
  • In conclusion, this unusual indication of liver transplantation underlines the interest of this therapeutic approach for benign tumors for which the multiplicity of the lesions and their huge volume prevent any attempt at surgical resection.

  • BACKGROUND: With the routine use of improved imaging modalities, more benign liver lesions are detected nowadays.
  • METHODS: A Medline search of studies relevant to imaging diagnosis and management of the most common, benign, solid and non-solid liver lesions was undertaken.
  • The authors' own experiences with benign liver lesions were also taken into account.
  • The use of tissue-specific contrast media, which has clearly improved the accuracy of highly advanced radiological techniques, may be helpful during differential diagnosis.
  • Once having established an accurate diagnosis, surgery is rarely indicated for a benign liver lesion because of its asymptomatic nature.

  • Up to now only a very few cases of PEComa of the liver have been described worldwide.
  • Based on the above findings, a diagnosis of a primary clear cell "sugar" tumor was established.
  • A long-term periodic follow-up is reasonable in all cases presenting with PEComa.

  • [Title] Unusual benign focal liver lesions: findings on real-time contrast-enhanced sonography.
  • OBJECTIVE: This presentation aims to provide an overview of the manifestations of some unusual benign focal liver lesions (FLLs) on low-acoustic power contrast-enhanced sonography (CES) with a sulfur hexafluoride contrast agent.
  • The pathologic examinations proved that they were intrahepatic biliary cystadenoma (n = 1), angiomyolipoma (AML; n = 4), lipoma (n = 1), biliary epithelial dysplasia (n = 1), a fungal inflammatory mass (n = 1), tuberculoma (n = 2), an inflammatory pseudotumor (n = 7), sarcoidosis (n = 1), solitary necrotic nodules (n = 2), peliosis hepatis (n = 2), and focal fibrosis after surgery (n = 4).
  • RESULTS: Contrast-enhanced sonography was beneficial in leading to a diagnosis of benignity for some lesions showing hyperenhancement during the arterial phase and sustained enhancement during the portal or late phase, such as liver AML and lipoma.
  • On the other hand, for those lesions showing hyperenhancement, isoenhancement, or hypoenhancement during the arterial phase and hypoenhancement during the late phase, including intrahepatic biliary cystadenoma, biliary epithelial dysplasia, infected liver diseases, the inflammatory pseudotumor, sarcoidosis, and peliosis hepatis, the differential diagnosis between benignity and malignancy was difficult, and pathologic tests were mandatory.
  • CONCLUSIONS: The CES features of unusual benign FLLs may enrich knowledge when performing CES examinations for characterization and may provide clues for a specific diagnosis of an individual lesion such as liver AML.

  • PEComas (tumours showing perivascular epithelioid cell differentiation) are a family of related mesenchymal neoplasms that include angiomyolipoma, lymphangiomyomatosis, clear cell "sugar" tumour of the lung, and a group of rare, morphologically and immunophenotypically similar lesions arising at a variety of visceral and soft tissue sites.
  • This review examines the members of the PEComa family, with an emphasis on lesions arising outside of the kidney, lung and liver, and discusses preliminary evidence for pathological features that might predict malignant behaviour.

  • [Title] Fat-containing lesions of the liver: cross-sectional imaging findings with emphasis on MRI.
  • OBJECTIVE: The purpose of this pictorial essay is to identify different types of liver lesions that contain fat.
  • Cross-sectional imaging findings of fat- or lipid-containing lesions can help in characterizing focal liver lesions.
  • We searched our archive retrospectively and reviewed the literature for fat-containing liver lesions and identified 16 different types.
  • CONCLUSION: These lesions can contain macroscopic fat (i.e., angiomyolipoma, lipoma, liposarcoma, hydatid cyst, lipopeliosis, adrenal rest tumor, pseudolipoma, hepatic teratoma, pericaval fat, extramedullary hematopoiesis, and metastases) or intracellular lipid (i.e., focal steatosis, adenoma, focal nodular hyperplasia, regenerative nodules, and hepatocellular carcinoma).
  • CT, MRI, and sonographic findings of these lesions can help in characterization by allowing specific diagnosis or narrowing the differential diagnosis of liver lesions.

  • [Title] Imaging features of hepatic angiomyolipomas.
  • We review the imaging appearances of hepatic angiomyolipomas in patients with and without tuberous sclerosis.
  • Sporadic hepatic angiomyolipomas have a varied appearance because of the inconstant proportion of fat, making confident imaging diagnosis difficult and necessitating biopsy in many cases.
  • In patients with tuberous sclerosis, hepatic angiomyolipomas have a more consistent imaging appearance and, together with other features of the syndrome, can be more easily diagnosed.

  • Perivascular epithelioid cell (PEC) is a unique cell which expresses both myogenic and melanocytic markers, and forms PEComa.
  • A 36-year-old woman presented with a 35 mm-diameter liver tumor.
  • Contrast-enhanced ultrasonography using the newly developed enhancing reagent, Sonazoid, clearly demonstrated early-phase enhancement of the tumor and rapid drainage of the reagent to veins, suggesting a PEComa.
  • Lateral segmentectomy of the liver was performed.
  • Histologically, epithelioid tumor cells around the vessels were immunostained with both HMB-45 and alpha-smooth muscle actin, confirming the diagnosis of PEComa.

  • [Title] The hypointense liver lesion on T2-weighted MR images and what it means.
  • The vast majority of focal liver lesions are hyperintense on T2-weighted magnetic resonance (MR) images.
  • Rarely, however, hepatic nodules may appear totally or partially hypointense on those images.
  • Although rare, low signal intensity relative to surrounding liver on T2-weighted images may be seen in a wide spectrum of lesions.
  • On fat-suppressed T2-weighted images, nodules with a lipomatous component, such as lipoma, angiomyolipoma, hepatocellular adenoma, and hepatocellular carcinoma may also appear partially or totally hypointense.
  • The conjunction of other MR imaging findings and their integration in the clinical setting may allow a correct diagnosis in a considerable proportion of cases.
  • The aims of this work are to discuss the causes and mechanisms of hypointensity of liver lesions on T2-weighted images and proposing an algorithm for classification that may be useful as a quick reminder for the interested reader.

  • [Title] Adequate symptom relief justifies hepatic resection for benign disease.
  • BACKGROUND: The purpose of this study was to evaluate the long-term results of partial liver resection for benign liver lesions.
  • METHODS: All patients operated on for benign liver lesions from 1991 to 2002 were included.
  • The diagnosis was haemangioma in 8 patients, FNH in 6, HCA in 13 and angiomyolipoma in 1.
  • CONCLUSION: Long-term follow up after liver surgery for benign liver lesions shows considerable symptom relief and patient satisfaction.

  • INTRODUCTION: Tuberous sclerosis complex (TSC) is a genetic disorder characterised by lesions affecting brain, skin, eyes and internal organs--kidneys, heart, liver and lungs.
  • CASE REPORT: A case of 17-year-old boy with delayed diagnosis of tuberous sclerosis complex with angiomyolipomas and cysts of the kidneys has been described.
  • CONCLUSION: The authors would like to underlina a very rare incidence of tuberous sclerosis complex and associated renal angiomyolipomas in children, the possibility to maintain normal kidney function for prolonged time despite intensified renal pathology, the need for periodic abdominal imaging and significantly delayed diagnosis in the described case.

  • [Title] The association of pulmonary lymphangioleiomyomatosis with renal and hepatic angiomyolipomas in a prepubertal girl: a previously unreported entity.
  • A prepubertal 13-year-old girl with PLAM associated with renal and hepatic angiomyolipomas who was treated by nephroureterectomy and thoracoscopic pleurodesis is presented.
  • To the best of our knowledge, this is the first reported case of PLAM associated with renal and hepatic angiomyolipomas at the prepubertal age.
  • After evaluating the clinicopathologic features of this rare entity, the authors conclude that PLAM should be considered in the differential diagnosis of cystic pulmonary pathologies in children, particularly teenagers.
  • The most important clinical aid is to bear this rare entity in mind when a child presents with renal and/or hepatic angiomyolipomas.

  • Angiomyolipomas are abdominal masses made up of muscle vessels and adipose tissues that grow mostly in proximity to kidneys and liver.
  • This study shows that angiomyolipoma-derived human smooth muscle TSC2-/- cells express the apoptosis inhibitor protein survivin when exposed to IGF-1.
  • The autocrine release of IGF-1 may therefore be a powerful mechanism of survival of the tightly packed cells in the thick-walled vessels of TSC angiomyolipoma and in lymphangioleiomyomatosis (LAM) nodules.

  • However, a distinctive variant of PEComa, designated "sclerosing PEComa," has only recently been described in the literature.
  • All 13 of the cases of sclerosing PEComa reported thus far have been in women (mean age of 49 y), with a predilection for the retroperitoneum.
  • We report the first case of sclerosing PEComa arising in the uterine adnexa, with high-grade malignant transformation.

  • PURPOSE: The purpose of this study was to assess real-time contrast-enhanced ultrasound in patients with hepatic angiomyolipomas with respect to contrast-enhancing kinetics and enhancement patterns.
  • All the 19 tumors were surgically resected and immunohistochemically proven sporadic hepatic angiomyolipomas.
  • Two lesions (10.5%) were detected inhomogeneously hypoenhancement compared to liver parenchyma during arterial, portal, and late phases, with only punctiform internal enhancement.
  • Early strong enhancement in arterial phase, rapid washout of contrast agent, and appear hypoechoic to surrounding liver tissue during portal or late phase was not at all observed.
  • CONCLUSION: Real-time contrast-enhanced ultrasonography can demonstrate typical imaging characteristics of hepatic angiomyolipomas in most cases, that is, inhomogeneous hyperenhancing pattern in arterial phase, prolonged hyperenhancement during portal and late phase with smooth and well-defined margin.
  • This real-time dynamic imaging technique may therefore improve noninvasive characterization and differentiation of this rare, benign, hepatic mesenchymal neoplasm.

  • The diagnosis is usually established on the basis of diagnostic criteria applied to physical or radiologic findings.
  • Because the classical triad of epilepsy, mental retardation, and adenoma sebaceum is uncommonly seen at clinical examination, radiologic examinations can play an important role in the diagnosis of tuberous sclerosis and in treatment.
  • Cardiac rhabdomyoma, renal angiomyolipoma, and neurologic involvement encompassing cortical or subependymal tubers and white matter abnormalities are the common radiologic findings.
  • Moreover, tuberous sclerosis can involve bone, liver, and the alimentary tract.
  • Familiarity with the clinical and radiologic findings in various organs is crucial in diagnosis and treatment.

  • Perivascular epithelioid cell tumor (PEComa) is a rare tumor which arises from mesenchymal tissues.
  • It is predominant in the uterus, but very rare in the liver.
  • To the best of our knowledge, less than 5 cases of PEComa of the liver have been reported.
  • Herein we present two pathologically proven cases of PEComa of the liver, retrospectively analyze their clinical and imaging features, and review the literature.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Clinical role of laparoscopic hepatectomy using vessel sealer and soft coagulation for small hepatic tumors suspected of malignancy.
  • To date, however, few reports have been published on a clinical usefulness of laproscopic hepatectomy using vessel sealer (VS) and soft-coagulation system (SC) for small hepatic tumors suspected of malignancy.
  • METHODOLOGY: Case 1; A 58-year-old man presented with a small hepatic tumor, detected during a medical examination.
  • Image sutdies including ultrasonography, magnetic resonance image and angiography suspected it as hepatocellular carcinoma (HCC), adenoma, angiomyolipoma, or focal nodular hyperplasia (FNH).
  • Histopathological diagnosis was FNH.
  • Case 2; A 57-year-old man presented with a small hepatic tumor, detected during a medical examination.
  • Histopathological diagnosis was HCC.
  • Case 3; A 59-year old man with a history of early colon cancer presented with a small hepatic tumor, detected during a routine check-up.
  • Histopathological diagnosis was adenocarcinoma.
  • Glisson's trunk and the left hepatic vain were transected with endo-linear staplers.
  • DISCUSSIONS: It has been difficult to obtain a biopsy specimen from small lesions and make a denifite diagnosis even with the specimen.
  • CONCLUSIONS: Laparoscopic hepatectomy using VS and SC may be a less invasive and radical treatment as well as an useful diagnostic modality for small hepatic tumors suspected of malignancy.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • In 200 consecutive clinical patients (122 men and 78 women: mean age, 61.9 years), ADCs were calculated for liver (four segments), spleen, pancreas (head, body, tail), gallbladder, renal parenchyma, and back muscle, and then compared to evaluate the reliability of clinical ADC measurements with parallel imaging.
  • Degraded image quality prevented ADC measurement of the left hepatic lobe and pancreas in 7-18 patients.
  • There was no significant difference among ADCs of four liver segments (1.50 +/- 0.24 [SD] x 10(-3) mm2/s - 1.56 +/- 0.31 x 10(-3) mm2/s) and between ADCs of the right and left kidneys (2.65 +/- 0.30 x 10(-3) mm2/s, 2.59 +/- 0.33 x 10(-3) mm2/s).
  • ADC of renal angiomyolipoma was significantly lower than those of renal cell carcinoma and healthy renal parenchyma (p < 0.0005).
