[Cystic meningioma simulating glioblastoma in x-ray computed tomography].
Seven cases of supratentorial meningiomas are reported. CT-Scan showed irregular hypo-hyperdense zones and features of intratumoral cysts. At surgery a well circumscribed tumor has always been found and easily removed "en bloc". In two cases stereotaxic biopsy was performed previously. CT-Scan findings of meningiomas with microcystic structure and/or necrotic areas may mimic a malignant glioma and lead to an incorrect presumptive diagnosis: then, both therapy and prognosis will be very different. It comes that stereotaxic biopsy is mandatory in all suspected cases of cerebral tumors, in the absence of classical angiographic patterns.
