Intraparenchymal Meningioma in a Child

—Case Report—

Abstract

A 10-year-old boy presented with an intraparenchymal meningioma, which had no attachment to the dura, manifesting as grand-mal seizure. Neurological examination showed no abnormalities. Magnetic resonance (MR) imaging revealed a round, well demarcated mass in the left frontal lobe, which was homogeneously enhanced. The tumor appeared to be intraaxial and caused marked peritumoral white matter edema. At operation, the mass was totally embedded in the frontal lobe and gross total resection was accomplished. The histological diagnosis was meningothelial meningioma with chordoid components in World Health Organization grade I. His postoperative course was uneventful and postoperative MR imaging revealed no residual tumor. Intraparenchymal meningioma should be considered in the differential diagnosis of an intraaxial lesion in a child.
