Persistent Primitive Hypoglossal Artery Presenting with Perimesencephalic Nonaneurysmal Subarachnoid Hemorrhage: A Case Report and Review of Literature

ConclusionWe present a case of PPHA associated with PNSAH and review the literature. The main cause for the PPHA related to SAH is an aneurysm. The four vessels angiography helped rule out an aneurysm that is associated with a poorer prognosis and requires immediate active management. It is, therefore, essential for physicians to be aware of the increased incidence of aneurysms in PPHA to make the correct diagnosis.
