Ruptured distal anterior choroidal artery aneurysm

This report describes a patient with a rare distal anterior choroidal artery (AChoA) aneurysm that developed a right intracerebral haematoma and intraventricular haemorrhage and was treated by surgical exploration and clipping via a transtemporal/ventricular approach. The patient was discharged neurologically intact. We review the literature related to these rare aneurysms within the temporal horn, and the surgical anatomy of the AChoA.
