Abstract

Microcystic meningioma, a distinct morphological variant of meningiomas, is histologically characterized by a vacuolated appearance with multiple cystic spaces lined by vacuolated or stellate-shaped tumor cells. This unusual variant was originally described by Masson, who labeled it "humid". The clinical and morphological findings point toward a benign course. And these unusual morphological variants of meningioma are potentially curable tumor. But there is no definitive method for preoperatively differentiating microcystic meningioma from the malignant glioma. We report a case of microcystic meningioma occurring in the left frontal area of 74 year old woman, with malignant clinical nature.
