A case of basal ganglia meningioma

Abstract

We report a rare case of the subcortical meningioma located in basal ganglia without dural attachment which was successfully removed by surgery. A 15-year-old girl with two months history of slowly progressing right sided weakness and motor dysphasia had the well-circumscribed, homogeneously enhancing solid mass with peritumoral edema in the left basal ganglia without any attachment to the sylvian fissure in magnetic resonance imaging. Total resection was done without complications and the histological diagnosis of the mass was a meningothelial meningioma. The possibility of the meningioma should be considered when the well-circumscribed insular mass has characteristic peritumoral edema and surgical removal should be the treatment of choice.
