Anomalous origin of the ophthalmic artery from the anterior cerebral artery: Case report

Abstract

A 39-year-old woman presented with left visual disturbance and diplopia. Magnetic resonance imaging revealed a well-enhanced tumor in the left tentorium, cavernous sinus, and suprasellar region. Angiography demonstrated an abnormal origin of the ophthalmic artery from the anterior cerebral artery. The tumor was partially removed by left frontotemporal craniotomy with orbitozygomatic osteotomy. Intraoperatively, the anomalous origin of the ophthalmic artery was confirmed. This anatomical variation is extremely rare.
