ABSTRACT=The persistent primitive hypoglossal artery (PPHA) is the second most common persistent carotid-vertebrobasilar anastomosis, with an incidence of 0.027-0.26%.PPHAs change the hemodynamics of the carotid and vertebral-basilar system and may be associated with intracranial vascular anomalies, but basilar bifurcation aneurysms were rarely reported. We describe the first case of a PPHA as the sole supply to the brain associated with a basilar bifurcation aneurysm and review the literature. We reported a 34-year-old woman who presented with subarachnoid hemorrhage due to a ruptured basilar bifurcation aneurysm. Digital subtraction arteriogram revealed a right persistent primitive hypoglossal artery as the sole supply to the brain. The aneurysm was successfully clipped under intraoperative neurophysiology.
