Congenital Hypoplasia of the Bilateral Internal Carotid Artery: A Case Report

ABSTRACT

Congenital agenesis, aplasia or hypoplasia of the internal carotid artery is rare vascular disease and usually combine with intracranial aneurysm, subarachnoid hemorrhage, or intracerebral hemorrhage. We report a case of bilateral congenital hypoplasia of internal carotid artery in a 36 year-old woman presented with semicomatose mentality. The brain computed tomography(CT) revealed intracerebral hemorrhage with intraventricular hemorrhage, and cerebral angiography showed hypoplasia of bilateral internal carotid artery without narrowing of the bony carotid canal on the temporal bone CT.
