Childhood meningioma associated with meningio-angiomatosis. Case report.

Abstract

This paper reports childhood meningioma in association with meningioangiomatosis. The patient was an 11-month-old baby boy who presented with a left focal seizure. He had no stigmata of neurofibromatosis. Computerized tomography and magnetic resonance imaging revealed an extra-axial, contrast-enhancing mass in the interhemispheric fissure which indented the right frontal lobe. The tumor was totally removed. Microscopically, the lesion was a fibrous and transitional meningioma with foci of necrosis and scattered mitotic figures. The adherent neural parenchyma showed the histological features of meningioangiomatosis. It is concluded that meningioangiomatosis may accompany childhood meningiomas more often than is generally appreciated.
