Abstract
To report a case of optic tract compression caused by a dolichoectatic basilar artery. Observational case report. A 74-year-old man with progressive loss of vision over 13 years and no other neurologic signs or symptoms was found to have bilateral optic nerve head pallor and a left homonymous hemianopia. Magnetic resonance imaging and angiography revealed a severe dolichoectatic basilar artery compressing the right optic tract. Basilar artery dolichoectasia may rarely cause compression of the optic tract and progressive visual loss.
