  • Meningioma is a common intracranial tumor, originating from the meninges of the skull or spinal canal.
  • Most meningiomas are benign tumors, however atypical or anaplastic tumors can be found in 6% of cases.
  • Patients with asymptomatic small benign meningiomas can be followed without therapy, but in symptomatic patients complete surgical resection should be performed.
  • For recurrent previously resected tumors re-resection is recommended followed by radiotherapy in selected cases.
  • Antiprogesterone treatment can also be considered in recurrent benign meningiomas.
  • Immunotherapy with interferon-alpha and chemotherapy should be reserved for all cases of recurrent meningiomas (benign, atypical, and malignant) when all the standard therapies have failed or contraindicated.

  • INTRODUCTION: Meningiomas are dural-based brain tumors that are typically histologically benign.
  • Volumetric measurement may be more accurate because tumors may grow in different directions than the planimetric axes.
  • METHODS: Twenty-one patients (with 22 tumors) had serial MRI brain scans available for review.
  • We reviewed the charts and measured tumor dimensions on the MRI scans.
  • Patient demographics, tumor location, and special radiologic characteristics (calcification, T2 hypointensity, dural tail, mass effect, and midline shift) were compared to the volumetric growth rate.
  • RESULTS: Patients included 17 females and 4 males; age at diagnosis 36 to 74 years (mean 61).
  • Most tumors were located in the convexity (27.27 %), sphenoid wing (27.27 %), or cerebellopontine angle (13.04 %).
  • There were no significant associations between other tumor locations, age, gender, or radiologic characteristics and volumetric growth.
  • CONCLUSIONS: The mean volumetric growth rate was significantly greater than the planimetric growth rate, suggesting that volumetric measurement conveys more information and is superior in assessing tumor growth.

  • Meningeal melanocytoma refers to the uncommon clinical appearance of a generally benign tumour deriving from leptomeningeal melanocytes.
  • Meningeal spread of this tumour is very rarely observed.
  • We present the case of a 38-year-old man with meningeal melanocytoma of the cerebello-pontine angle, who showed a biphasic course of this disease, with a stable period followed by a steady progress within few months.
  • After surgical resection of the melancytoma in the left skull base and of a first local recurrence five years later, a second local recurrence occurred 6 years after diagnosis, with intracerebral and spinal meningeal seeding.
  • This tumor did not respond to a combined radiochemotherapy including oral temozolomide, and the patient died 5 months after starting treatment for this relapse.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • PURPOSE: This study aims to verify the reliability of diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) measurements to differentiate benign from atypical/malignant meningiomas and among different sub-types.
  • DWI signal intensity of tumors was classified as hypo-, iso- or hyper-intense to grey matter.
  • RESULTS: Meningiomas were histologically graded as malignant (1%), atypical (21.5%) and benign (77.5%).
  • Meningothelial, transitional and fibrous were the most frequent benign sub-types (44, 16 and 10 cases, respectively).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Cranial base glioneuronal heterotopia is a nest or linear array of glioneuronal tissue within the basal meninges.
  • It frequently mimics tumors and may extend through basal skull bones into extracranial soft tissues.
  • Magnetic resonance imaging showed a large, predominantly solid, minimally enhancing tumor in the anterior cranial fossa extending into the suprasellar region as well as into the right and left middle fossae.
  • The gross tumor was totally resected through bifrontal craniotomy.
  • CONCLUSIONS: Although uncommon, diagnosis of intracranial extracerebral glioneuronal heterotopia should be strongly ascertained while evaluating intracranial space-occupying lesions during the prenatal period and infancy.
  • It needs to be distinguished histologically from teratoma and primary central nervous system tumors.
  • Prenatal screening for early diagnosis of the lesion is vital.
  • The location of the lesion and its relationship to the surrounding structures should lead to an accurate diagnosis in the majority of cases.
  • Long-term prognosis is excellent in view of the benign nature and extraaxial origin of the lesion.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Intermediate grade meningeal melanocytoma of cervical spine.
  • BACKGROUND: Meningeal melanocytoma is a rare, benign melanotic tumor of the leptomeninges, which occurs anywhere in the cranial or spinal regions but most commonly in supratentorial and thoracic spine regions.
  • The literature on this entity consists of case reports; therefore, there is no agreement on the most effective therapy of this tumor, although total excision seems to be the best therapeutic option.
  • CASE HISTORY: We report a 17-year-old girl with intermediate grade meningeal melanocytoma involving the C6 nerve root with spinal cord compression resulted in progressive tetraparesis.
  • The tumor was removed subtotally through cervical laminotomy followed by rapid improvement of most neurological deficits.
  • This tumor was unusual because of its very hyperintense homogenous signal on T1-weighted images, invasion of the arachnoid membrane, and extension into the neural foramina.
  • Black dots on the surface of the cord were thought to represent an organized blood clot until the frozen section suggested a melanocytic tumor.
  • DISCUSSION: We discuss the distinction of meningeal melanocytoma from other melanocytic tumors of the leptomeninges.
  • CONCLUSION: Melanocytic tumors should be considered in the differential diagnosis when a hyperintense lesion of the leptomeninges is identified on T1-weighted images or a very dark mass similar to charcoal or organized hematoma is found in the surgical field.
  • The best management is complete tumor resection, but radiotherapy is reserved in cases of subtotal resection and multiple lesions.
  • Locally aggressive nature of tumor and possibility of recurrence warrant regular follow-up.

  • METHODS: We examined the mRNA and protein expression of human ZIC1, ZIC2, ZIC3, ZIC4 and ZIC5 genes in meningiomas in comparison to other brain tumors, using RT-PCR, analysis of published microarray data, and immunostaining.
  • The expression level of ZIC1 in public microarray data was greater in meningiomas classified as World Health Organization Grade II (atypical) than those classified as Grade I (benign).
  • In normal meninges, ZIC-like immunoreactivities were detected in vimentin-expressing arachnoid cells both in human and mouse.
  • The pattern of ZIC expression in both of these tumor types may reflect the properties of the tissues from which the tumors are derived.

  • Our initial clinical observations of this case suggested the possibility of primary cutaneous neonatal melanoma or skin metastasis from a melanoma in the meninges or elsewhere in the central nervous system.
  • Pagetoid arrays of naevus cells in the junctional zone and myxoid changes present in a significant portion of the dermis led to the diagnosis of proliferative nodules.
  • Distinct histological patterns seen in the proliferative nodules in our neonatal patient were useful to differentiate between benign pigmented nodular lesions in a giant congenital naevus and malignant melanoma, and reduced the chance of misdiagnosis.

  • Spinal tumors can be intramedullary, intradural (within the meninges), or extradural (between the meninges and the bones), or they may extend secondary to the spine from other locations.
  • Vertebral hemangioma represents the most common benign tumor of the spine.
  • Metastases, lymphoma, and multiple myeloma are the most frequent malignant spinal tumors.
  • Primary osseous tumors of the spine, in contrast, are rare conditions but may demonstrate typical imaging findings.
  • For the differential diagnosis, the patient's age, the topographic localization of the mass, and morphologic features of the lesion as depicted by computed tomography and magnetic resonance imaging play important roles.

  • [Title] A meningeal myofibroblastic neoplasm related to solitary fibrous tumour and associated with a malignant neuroblastic element.
  • BACKGROUND: Solitary fibrous tumour (SFT) is a rare mesenchymal tumour now described at many locations, including the meninges.
  • Intracranial SFT closely resembles meningioma clinically and radiologically, and, like meningioma, reports of meningeal SFT suggest a relatively benign behaviour after complete resection.
  • CLINICAL PRESENTATION: The case is reported of a 60-year-old man with an anterior cranial fossa meningeal-based mass, which was resected.
  • Recurrence of the tumour with extracranial extension 9 years later resulted in death of the patient.
  • Histological examination revealed similar biphasic epithelioid and spindled CD34-immunopositive appearance to the earlier tumour, but in addition showed a high-grade element resembling olfactory neuroblastoma.
  • CONCLUSION: This case report is of a meningeal-based mesenchymal neoplasm with histological similarities to SFT.
  • In addition, recurrence of the tumour with a high-grade neuroblastic element has, to our knowledge, not previously been described in SFT.

  • Meningothelial meningiomas (MMs) accounted for 63.5% (464/731) of the Grade I tumors.
  • Analysis of the increasingly available data on genetic and topographic characteristics of MMs suggests that they may represent a unique entity, contrary to the prevailing belief that all benign meningiomas are identical tumors.

  • [Title] Modeling NF2 with human arachnoidal and meningioma cell culture systems: NF2 silencing reflects the benign character of tumor growth.
  • Meningiomas, common tumors arising from arachnoidal cells of the meninges, may occur sporadically, or in association with the inherited disorder, neurofibromatosis 2 (NF2).
  • Most sporadic meningiomas result from NF2 inactivation, resulting in loss of tumor suppressor merlin, implicated in regulating membrane-cytoskeletal organization.
  • To investigate merlin function in an authentic target cell type for NF2 tumor formation, we established primary cultures from genetically-matched meningioma and normal arachnoidal tissues.
  • Merlin-deficient meningioma cells displayed cytoskeletal and cell contact defects, altered cell morphology and growth properties, most notably cell senescence, implicating the activation of senescence pathways in limiting benign meningioma growth.

  • [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.
  • The second patient carried a diagnosis of marginal zone lymphoma but then presented 5 years later with symptoms referable to a large dural-based mass with significant surrounding edema, prompting surgical removal.
  • 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.
  • In this paper, we report a rare case of a 29-year-old boy who presented with papillary meningioma originating from the posterior fossa meninges.
  • After a long, disease-free period, however, spinal drop metastases occurred 32 months after resection of the primary tumor.
  • The primary and metastatic lesions had a similar histological appearance, meaning that multiple spinal metastatic lesions occurred through CSF route even after a gross total resection of the tumor.
  • Tumor seeding during surgery is the evident reason for spinal metastasis, although we strictly adhered to the standard precautions for operations for malignant tumors such as obstruction of the cisterna magna with cotton paddies, and changing surgical gloves and instruments during the operation.
  • In this report, we briefly discuss an exceedingly rare variant of meningioma, the papillary variant, and suggest a new approach, a CSF sampling, in the management of both malignant and benign meningiomas.
  • CSF sampling allows for the early detection of metastasis and of tumor cells before metastasis has occurred, thus allowing treatment to begin as soon as possible.
  • Furthermore, we discussed that meningiomas are tumors that are not as benign as initially thought.

  • 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.

  • INTRODUCTION: Meningiomas are common intracranial neoplasms which originate from the soft meninges, precisely from meningeal arachnoidal cells.
  • It included 490 consecutive patients of both sexes with diagnosed intracranial tumors and undergoing surgical treatment at the Neurosurgery Clinic of the Clinical Center of Vojvodina.
  • Out of 490 patients with diagnosed intracranial tumors, 137 (27.96%) were diagnosed to have meningiomas.
  • In regard to other histological types of intracranial tumors, meningiomas were more frequent in females (36.3%).
  • The commonest histological types of meningiomas were benign meningiomas (93.4%).
  • Malignant histological types of meningiomas were more common in males (83.3%), whereas benign histological types were more common in females (64.1%).
  • The tumor is located in the left frontal region.
  • On histology it is benign, transitional type of meningiomas.

  • BACKGROUND AND PURPOSE: Although meningiomas are typically benign, they occasionally behave in an aggressive fashion and carry a less favorable prognosis.
  • Tumor grading was based on new WHO criteria.
  • There were eleven men and five women with a mean age of 54 years.
  • Six patients (37.5%) experienced tumor recurrence after a mean period of 27.2 months in spite of gross total resection.
  • By comparing the proliferation rate in four cases with atypical meningioma operated twice, the recurrent tumor had a higher proliferation rate than the first tumor in three cases.
  • CONCLUSION: Considering the higher rate of recurrence in aggressive meningiomas even after radical surgical excision and the possibility that the recurrent tumor is more aggressive than the original one, surgery should be combined with postoperative fractionated radiotherapy to improve local tumor control.

  • Several different types of tumors, benign and malignant, have been identified in the central nervous system (CNS).
  • The prognoses for these tumors are related to several factors, such as the age of the patient and the location and histology of the tumor.
  • In adults, about half of all CNS tumors are malignant, whereas in pediatric patients, more than 75% are malignant.
  • For most benign CNS tumors that require treatment, neurosurgeons can offer curative resections or at least provide significant relief from mass effect.
  • Unfortunately, we still lack effective treatments for most primary and secondary malignant CNS tumors.
  • However, the past decade has witnessed an explosion in the understanding of the early molecular events in malignant primary CNS tumors, and for the first time in history, oncologists are seeing that a plethora of new therapies targeting these molecular events are being tested in clinical trials.
  • There is hope on the horizon for the fight against these deadly tumors.
  • The distribution of CNS tumors by location has remained constant for numerous years.
  • The majority of primary CNS tumors arise in the major cortical lobes.
  • Twenty nine percent of primary CNS tumors arise from the dural meninges that encase the CNS structures.
  • The vast majority of these are meningiomas, of which over 90% are benign.
  • About 10% of primary CNS tumors are found in the sella turcica region, where the pituitary gland resides.
  • Other much less common sites of primary CNS tumors include the pineal region, ventricular system, cerebellum, brain stem, cranial nerves, and spinal cord.
  • The distribution of CNS tumors by histology has seen a slight increase in more malignant tumors over the past decade, possibly due to increased neuroimaging practices or environmental exposures.
  • Arising from glial cells, gliomas represent over 36% of all primary CNS tumors and consist of astrocytomas, oligodendrogliomas, ependymomas, mixed gliomas, and neuroepithelial tumors.
  • The benign meningiomas make up 32% of primary CNS tumors, followed by nerve sheath tumors and pituitary tumors.
  • Primary CNS lymphomas, embryonal tumors, and craniopharyngiomas are uncommon.

  • [Title] Downregulated microRNA-200a in meningiomas promotes tumor growth by reducing E-cadherin and activating the Wnt/beta-catenin signaling pathway.
  • Meningiomas, one of the most common human brain tumors, are derived from arachnoidal cells associated with brain meninges, are usually benign, and are frequently associated with neurofibromatosis type 2.
  • Here, we define a typical human meningioma microRNA (miRNA) profile and characterize the effects of one downregulated miRNA, miR-200a, on tumor growth.
  • Elevated levels of miR-200a inhibited meningioma cell growth in culture and in a tumor model in vivo.
  • Thus, miR-200a appears to act as a multifunctional tumor suppressor miRNA in meningiomas through effects on the E-cadherin and Wnt/beta-catenin signaling pathways.
  • This reveals a previously unrecognized signaling cascade involved in meningioma tumor development and highlights a novel molecular interaction between miR-200a and Wnt signaling, thereby providing insights into novel therapies for meningiomas.

  • [Title] Supratentorial meningeal melanocytoma mimicking a convexity meningioma.
  • OBJECTIVE AND IMPORTANCE: Meningeal melanocytomas are rare benign neuro-ectodermal tumors arising from melanocytic cells in the leptomeninges.
  • Thus, most reported cases of meningeal melanocytomas are located in the posterior fossa and the spinal cord, respectively.
  • CLINICAL PRESENTATION: We report on the rare case of a 55-year-old male patient with a large supratentorial meningeal melanocytoma mimicking a convexity meningioma and a smaller, similarly dura based lesion in the posterior fossa.
  • INTERVENTION: Tumor control to date was achieved by surgery of the large lesion and radiosurgery of the small lesion.
  • CONCLUSION: Complete tumor resection may be advantageous and second or recurrent lesions may be managed by repeat surgery or stereotactic radiosurgery.

  • In a prospective study over a 16 month period, 20 of 242 patients presented with isolated CN manifestations, and were assessed for the following: primary site; CN symptoms and signs; length of time between primary diagnosis and neurological involvement; and survival following the neurological diagnosis.
  • They included meningeal carcinomatosis (10/16), brain stem metastases (3/16), primary brain astrocytomas (1/16), and metastases out of the central nervous system (2/16).
  • Although most of the isolated CN manifestations were due to systemic metastasis, in particular to the meninges, up to 20% were related to benign conditions.
