Abstract
A middle-aged adult presented to the hospital with a high-grade aneurysmal subarachnoid hemorrhage. The patient was treated with endovascular coil embolization of a ruptured basilar tip aneurysm. Angiography demonstrated multiple other aneurysms, including type I persistent primitive olfactory artery aneurysm. After complete recovery and return to independence, the patient underwent elective treatment of the persistent primitive olfactory artery aneurysm with endovascular placement of a flow diversion stent. Persistent primitive olfactory artery is an extremely rare variant of the anterior cerebral artery with an incidence of 0.14% and a known increased risk of aneurysm formation.
