Abstract

We report three cases of fibrous meningioma with central necrosis. A 42-year-old female with convulsions suffered from cerebral convexity meningioma, a 53-year-old female with left hemiparesis from falx meningioma, and a 68-year-old female with dizziness from cerebellar convexity meningioma were admitted to our hospital with acute onset of symptoms. They underwent gross total removal of the tumors. All cases were diagnosed as fibrous meningioma, with central necrosis without malignant findings. No tumoral recurrence was observed in all cases with a mean follow-up duration of 7.1 years. On the basis of these finding, it is suggested that the sudden occlusion of the main feeding artery caused central necrosis of the meningioma.
