Meningioma

A rare, mostly benign, primary tumor of the meninges (arachnoid cap cells), usually located in the supratentorial compartment, commonly appearing in the sixth and seventh decade of life, clinically silent in most cases or causing hyperostosis close to the tumor and resulting in focal bulging and localized pain in less than 10% of cases. Additional features may include headache, seizures, gradual personality changes (apathy and dementia), anosmia, impaired vision, exophthalmos, hearing loss, ataxia, dysmetria, hypotonia, nystagmus, and rarely spontaneous bleeding.

	In the 34 study patients, the pathologic entities were 9 gliomas (5 astrocytomas, 2 ependymomas, and 2 oligodendrogliomas), 9 germ cell tumors (7 germinomas, 1 entodermal sinus tumor, and 1 malignant teratoma), 8 pineal parenchymal tumors (3 pinealomas, 3 pinealoblastomas, 1 mixed pinealoma-pinealoblastoma, and 1 intermediate differentiation pineal tumor), 4 other malignant tumors (2 undifferentiated carcinomas, 1 malignant melanoma, and 1 non-Hodgkin's lymphoma), 2 meningiomas, and 2 nonneoplastic lesions (1 glial cyst and 1 inflammatory lesion).
