  • DEVELOPMENT AND CONCLUSIONS: Choline containing compounds using contralateral creatine and choline for normalization or ipsilateral N-acetyl-aspartate appeared to correlate best with the degree of tumor infiltration, regardless o tumor histological grade.
  • Magnetic resonance spectroscopy imaging (MRSI) seems more accurate than conventional magnetic resonance imaging (MRI) in defining indistinct tumor boundaries and quantifying the degree of tumor infiltration.
  • Angiogenesis, and increased vascular permeability, are characteristic of cerebral neoplasms; these processes can be imaged using perfusion MRI.
  • Most commonly, tumor perfusion is measured using rapid gradient T2-weighted imaging during bolus injection of gadolinium dimeglumine gadopentetate.
  • Cerebral blood volume increases with tumor grade, and maybe helpful in identifying tumor recurrence, and peri-tumoral edema, and distinguishing malignant from benign lesions.

MedlinePlus Health Information. consumer health - Brain Tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • It is a benign, generally well-delineated, WHO grade I tumour with favorable prognosis, which makes it different from diffuse astrocytomas, classified as higher grades of malignancy.
  • A case study of PA was presented in a young female patient, observed and treated at the Neurosurgical Department for the period of 10 years, during which time she had frequent surgical procedures due to recurrence and dissemination of the tumour.
  • Neuroradiological study revealed cerebral tumour in the right temporal lobe, then the first temporal lobe surgery followed by re-operation and radiotherapy was performed.
  • After 5 years local recurrence of the tumour appeared in the right temporal region.
  • The patient was operated and the tumour was totally removed.
  • Initially, the histopathological diagnosis of ganglioglioma was suggested for primary tumour, finally the diagnosis of pilocytic astrocytoma for both recurrent and primary tumour was established.
  • The spinal tumour was surgically treated in both locations; the last operation was done 10 years after surgery of the primary temporal lobe tumour.
  • Histopathological examinations of the excised foci from spinal canal revealed neoplasm consistent with WHO grade I pilocytic astrocytoma.
  • The presented case indicates that despite the spread of the neoplastic process, a histopathologically benign tumour (WHO I grade) allows for long-term survival and observation period.
  • Unfortunately, multifocal tumour involving midline structures causes major neurological symptoms and deficits.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Initial experience of functional imaging of upper urinary tract neoplasm by diffusion-weighted magnetic resonance imaging.
  • OBJECTIVES: Diffusion-weighted (DW) magnetic resonance imaging (MRI) provides functional information widely used in the diagnosis of acute cerebral stroke.
  • The last patient was confirmed as experiencing benign stenosis.
  • The apparent diffusion coefficient (ADC) values of renal parenchyma, dilated collecting system, and tumor were calculated.
  • The case of benign stenosis had negative DW MRI.
  • The median (range) ADC value of the tumor (0.803 [0.412-0.958] x 10(-3) mm(2)/s) was significantly lower than those of the dilated collecting system (2.19 [1.42-2.40] x 10(-3)) and renal parenchyma (1.28 [0.922-1.45] x 10(-3), respectively (P < 0.01 and P < 0.01).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Radiosurgery for large-volume (> 10 cm3) benign meningiomas.
  • The average tumor volume was 17.5 cm3 (range 10.1-48.6 cm3); the average tumor margin dose was 15.1 Gy (range 12-18 Gy); and the mean follow-up duration was 70.1 months (range 12-199 months).
  • RESULTS: Tumor control was 99% at 3 years and 92% at 7 years after radiosurgery.
  • Thirty complications after radiosurgery were noted in 27 patients (23%), including 7 cases of seizures, 6 cases of hemiparesis, 5 cases of trigeminal injury, 4 cases of headaches, 3 cases of diplopia, 2 cases each of cerebral infarction and ataxia, and 1 case of hearing loss.

  • [Title] "Benign" metastatic meningioma: clinico-pathological analysis of one case metastasising to the lung and overview on the concepts of either primitive or metastatic meningiomas of the lung.
  • Lung "metastases" of benign meningiomas are rarely described events of biological and clinical interest.
  • Anamnesis revealed that the patient underwent a surgical resection of cerebral meningioma 12 years before.
  • The morphological and immunohistochemical features of this lesion, together with the similarity with the original cerebral tumour and its indolent evolution, led to a final diagnosis of "benign" meningioma metastatic to the lung.
  • They represent a typical example of "benign" tumours that may implant to the lung similar to other tumours, definitely considered benign but reported to rarely present unusual secondary localization.

  • Cerebrospinal metastases of benign choroid plexus papillomas (CPPs) are extremely rare.
  • Plain CT scan of the cranium revealed a partly calcified tumor filling the fourth ventricle and its right recess.
  • Cranial MRI showed an inhomogeneously contrast-enhancing tumor and leptomeningeal enhancement encasing the brain stem.
  • Complete resection of the tumor was carried out, and seedings to the floor of the fourth ventricle and cervico-medullary junction were found during the operation.
  • While intraoperative frozen section suggested pathology of papillary ependymoma or CPP, to our surprise, final histological examination revealed a benign choroid plexus papilloma.
  • This special case helps increase our understanding of benign CPPs and expands our differential diagnostic consideration of lesions with similar manifestations.

  • [Title] Tumor-to-tumor metastasis from hematopoietic neoplasms to meningiomas: report of two patients with significant cerebral edema.
  • BACKGROUND: Tumor-to-tumor metastasis is a rare, but well-reported, curiosity in which one type of primary neoplasm metastasizes to another primary tumor type within the same person.
  • OBJECTIVE: To report two examples of benign meningiomas in which metastatic tumor deposits from the patient's hematopoietic neoplasm to the meningioma caused significant peritumoral edema, necessitating semiemergent surgical resection.
  • RESULTS: One patient had multiple myeloma associated with extensive necrosis within his otherwise benign convexity meningioma; first diagnosis of his IgG, kappa-restricted plasma cell dyscrasia was made from this tumor-to-tumor meningioma specimen.
  • Dural marginal zone lymphoma was identified within epidural, intradural, and subdural spaces, in the same location as an underlying benign meningioma.
  • CONCLUSIONS: Although rare, neurosurgeons should be aware of the entity of tumor-to-tumor metastasis as, in large series, meningiomas are the third most frequent recipient tumor type and pituitary adenomas, the fifth most frequent, probably reflecting their rich vascularity.
  • In examples where the donor tumor type is a hematopoietic neoplasm, significant edema can be produced by the tumor-to-tumor metastasis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The purpose of this study is to evaluate the contribution of Magnetic Resonance Spectroscopy (MRS) and Perfusion-weighted MRI to distinguish malignant from benign tumours.
  • We included 55 patients diagnosed with single brain tumour by CT and MRI, and final histopathological verification of the tumour type: 25 were low-grade gliomas, 8 anaplastic gliomas, 11 glioblastomas, and 11 solitary metastases.
  • In MRS, we found significant differences in Choline/Creatine ratios in relation to the tumour type with the highest values in high-grade gliomas and metastases.
  • We found no significant differences in the relative cerebral blood volume (rCBV) for every type of tumour.
  • The mean rCBV was 1.24 for benign tumours and 1.5 for the malignant ones(1.24 for low-grade gliomas, 1.91 for anaplastic gliomas, 1.03 for glioblastomas, and 1.57 for metastases).
  • Perfusion MRI has not demonstrated predictive power to distinguish malignant from benign tumours.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Microarray gene expression profiling is a high-throughput system used to identify differentially expressed genes and regulation patterns, and to discover new tumor markers.
  • As the molecular pathogenesis of meningiomas and schwannomas, characterized by NF2 gene alterations, remains unclear and suitable molecular targets need to be identified, we used low density cDNA microarrays to establish expression patterns of 96 cancer-related genes on 23 schwannomas, 42 meningiomas and 3 normal cerebral meninges.
  • Results showed a high frequency of NF2 gene mutations (40%), increased 22q LOH as aggressiveness increased, frequent losses and gains by MLPA in benign meningiomas, and gene expression silencing by hypermethylation.
  • Unsupervised analyses identified 2 molecular subgroups for both meningiomas and schwannomas showing 38 and 20 differentially expressed genes, respectively, and 19 genes differentially expressed between the two tumor types.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.

  • In the recurrent lesion we identified pilocytic astrocytoma (PA) as a predominant component of the tumour.
  • Clinical presentation of the primary tumour consisted of partial simple seizures, while the recurrent tumour manifested with headache and vomiting.
  • We conclude that patients with incompletely removed DNT may suffer local recurrence of that tumour.

  • Gliofibromas are rare glio-mesenchymal tumors composed of astrocytic and benign mesenchymal components, which commonly occur in the first two decades of life.
  • Post-operatively, the residual tumor regrew to a size similar to the initial mass (4 cm x 3.6 cm x 3.5 cm), within one and a half years after the first surgery.
  • The histopathology of the tumor was similar on both occasions.
  • Although a poor prognosis has been characteristically noted in gliofibromas with high-grade glial component, but the present case had recurrence despite being of low-grade, thus highlighting the uncertain behaviour of this rare tumor.

  • The tumor was subtotally removed and was diagnosed to be a meningothelial meningioma.
  • Seven months after surgery, a recurrence of the tumor was confirmed.
  • The diagnosis of this recurrent tumor was an atypical meningioma.
  • The MIB-1 index and the percent of p53 protein-positive cells in the primary tumor were 4.6% and 35.4%, respectively, whereas those of the recurrent tumor were 34.7% and 33.1%, respectively.
  • These results suggest that the present case had a potentially malignant tumor in the early stage, although it had the histological features of benign meningiomas.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Postoperative MRI showed no evidence of residual tumor.
  • Two years later, MRI revealed a local recurrence and in addition a separated cystic tumor on the right side adjacent to the middle cerebral artery consistent with seeding along the surgical route.
  • On histopathological examination, both, the local recurrent tumor and the distant deposit turned out to be adamantinomatous craniopharyngiomas.
  • This deposit in the operative pathway was found to be an adamantinomatous craniopharyngioma, as was the initial tumor.
  • The recent control MRT revealed a right parietal intracranial tumor with peripheral contrast enhancement, which was located distant to the former craniotomy.
  • The tumor was removed and histopathological examination revealed an adamantinomatous craniopharyngioma in accordance with the initial tumor.
  • CONCLUSION: Although craniopharyngiomas exhibit a benign histopathological pattern, cerebrospinal fluid seeding along the surgical route or along the CSF pathways has been observed.
  • Ectopic recurrence of craniopharyngioma suggests that meticulous protection of the whole surgical field and careful handling of the tumor during the operation are required.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • PURPOSE: Desmoplastic infantile gangliogliomas (DIG) are rare benign intracranial neoplasms of early childhood with involvement of superficial cerebral cortex and leptomeninges.
  • The purpose of the study was to determine the alterations in metabolite ratios occurring in the neoplasm and combine with magnetic resonance (MR) imaging features to narrow down the diagnosis.
  • Single-voxel short TE (1)H MR spectroscopy was used to study the changes in metabolite ratios in the tumor.
  • RESULTS: Comparison of metabolite ratios between normal brain tissue and tumor-affected region showed lower N-acetyl aspartate to creatine (Cr; 1.58 vs.1.28), higher choline to Cr (0.82 vs.2.03), and no significant change in myo-inositol to Cr (0.42 vs.0.39).

  • INTRODUCTION: Hemangioblastomas are neoplasm of vascular type having benign characteristics.
  • Brain tumor was diagnosed by neuroimage techniques.
  • CONCLUSION: The most frecuent localization of hemangioblastomas is in vermix and cerebellum hemispheres.
  • The bulbar localization is infrequent (which represents less percentage than 5% of cerebral hemangioblastomas) likewise the clinical manifestation though hiccups.

  • Angiomatoid fibrous histiocytoma (AFH) is a rare soft-tissue neoplasm that most commonly appears in the limbs, typically affecting children and young adults.
  • The tumor has a propensity for local recurrence and recurrent hemorrhage but rarely for remote metastasis.
  • To date, only 2 reports have documented an intracranial occurrence of the tumor (1 of which was believed to be metastatic disease).
  • Initially misdiagnosed as a cavernous malformation and then an unusual meningioma, the tumor was finally correctly identified when there was a large enough intact resection specimen to reveal the characteristic histological pattern.
