Abstract

A hyperplastic anterior choroidal artery is a vascular anomaly where the anterior choroidal artery supplies the posterior cerebral artery territory. We report a case of subarachnoid hemorrhage from a hyperplastic anterior choroidal artery with tandem fusiform aneurysms. The patient underwent a temporal craniotomy and transcortical transventricular transchoroidal-fissure approach for clip reconstruction. This case illustrates an unusual cerebrovascular pathology and approach to the ambient cistern.
