title: Chiasmal cavernoma: a rare cause of acute visual loss improved by prompt surgery.
abstract: We report a 16-year-old healthy boy who presented with sudden loss of vision in both eyes, accompanied by a mild headache. Magnetic resonance imaging showed a chiasmal apoplexy. An urgent craniotomy revealed a cavernous malformation of the chiasm, which was evacuated. There was a subsequent dramatic improvement in bilateral visual acuity and visual field defects. This case report emphasizes the importance of rapid diagnosis and surgery of an anterior visual pathway cavernous malformation.
