A 1-year and 10-month-old girl presented with an intraparenchymal meningioma in the left frontal lobe manifesting as grand-mal seizures. Computed tomography and magnetic resonance images revealed a round, well-demarcated mass in the left frontal lobe which was homogeneously enhanced. Angiography showed the feeding arteries of the tumor from the middle cerebral artery. The preoperative diagnosis was an intraaxial tumor. At operation, the lesion was totally embedded in the frontal lobe without any connection to the overlying dura or the ventricular system. Some small feeders from the middle cerebral artery were coagulated and the tumor was totally removed. The histological diagnosis was fibroblastic meningioma. Her postoperative course was uneventful. She was doing well 2 years after surgery. Intraparenchymal meningiomas may be seen more frequently than expected in children. Absence of dural attachment is characteristic of pediatric meningiomas.
