Differential diagnosis of a solid cystic lesion in supratentorial location includes glioma,1 meningioma,2 metastatic tumor,3 or hemangioblastoma.1 Cystic meningioma is relatively a rare tumor.2 Among various histological variants of meningioma, the meningothelial type most frequently demonstrates cystic changes.3 Richly vascularized meningiomas of the angiomatous type were reported only in a fe...

The 5-aminolevulinic acid (5-ALA)-induced tumor fluorescence is a useful intraoperative marker for the diagnosis and the detection of various malignancies, but its use in meningioma is only reported infrequently. In meningioma, a complete resection of the tumor mass is crucial for the prevention of recurrence and postoperative morbidities. Deep sylvian meningioma is a rare type of meningioma wh...

The authors present a case of familial clear cell meningioma in which the proband is a child with an intraspinal tumor. The clear cell meningioma variant has recently been studied. The literature regarding clear cell meningioma is reviewed.

OBJECTIVE A rare subtype of meningioma, sclerosing meningioma is not included in the current World Health Organization classification of meningiomas and is classified into the category of other morphological variation subtypes. Sclerosing meningioma is often misdiagnosed to other non-benign meningioma or malignant neoplasm, so it is important to diagnose sclerosing type correctly. We analyzed t...

Since the atomic bomb explosions in Hiroshima and Nagasaki, high incidences of leukemia, thyroid cancer and other tumors have been reported as atomic bomb-induced tumors. We investigated the incidence of meningioma among Hiroshima atomic bomb survivors. Sixty-eight patients surgically treated for meningioma who had been within 2.0 km of the hypocenter of the explosion were identified. Six hundr...

Ionizing radiation is the most established risk factor for meningioma formation. Our aim was to evaluate the main effect of selected candidate genes on the development of meningioma and their possible interaction with ionizing radiation in the causation of this tumor. The total study population included 440 cases and controls: 150 meningioma patients who were irradiated for tinea capitis in chi...

Cells resembling bone marrow mesenchymal stem cells (BM-MSCs) have been isolated from glioma specimens; however, little is known about the existence of mesenchymal stem-like cells (MSLCs) in meningioma. Here, we hypothesized that cells similar to BM-MSCs exist in meningioma specimens and sought to investigate whether these putative meningioma stroma MSLCs (MS-MSLCs) could be isolated. To this e...

Meningioma merupakan jenis neoplasma intrakranial ekstraaksial yang paling umum dijumpai. Seiring dengan berkembangnya ilmu genomik, beberapa studi mulai meneliti asosiasi kejadian meningioma keberadaan single-nucleotide polymorphisms (SNPs). Penelitian ini bertujuan untuk melihat hubungan antara SNP risiko terjadinya meningioma. Penelusuran literatur dilakukan pada berbagai database kemudian d...

Clear-cell meningioma is a rare subtype of meningioma which occurs at a younger age and has a higher recurrence rate than other subtypes. We report two cases of clear-cell meningioma, one in the thoracolumbar spinal canal and the other in the cerebellopontine angle. Though the CT and MR imaging findings were not different from those of ordinary meningioma, after surgical removal the condition r...

introduction: meningioma is a benign and slowly-growing tumor that is responsible for 20% of brain neoplasms. it can be accompanied by some genetic disorders such as neurofibromatosis type 2 and is more common among women. as a space occupying lesion, it produces a wide range of signs and symptoms by compressing the adjacent and underlying tissues in the brain. trauma and viruses are possible e...
