Giant Meningioma Fed by the Anterior Choroidal Artery: Successful Removal Following Embolization —Case Report—

抄録

A 53-year-old female was admitted with apathy, left sensory and motor disturbance, left homonymous hemianopsia, and dressing apraxia. Computed tomography and magnetic resonance imaging showed a huge mass markedly enhanced in and around the right trigone. Cerebral angiography revealed rich vascularity of the tumor mainly fed by the right anterior choroidal artery. The feeding vessel was embolized with microfibrillar collagen after superselective catheterization. Seven days later, the tumor was totally removed with low blood loss. The histological diagnosis was fibroblastic meningioma. She was discharged without neurological deficit, except for left homonymous hemianopsia.
