Abstract

Agenesis and hypoplasia of the internal carotid artery (ICA) are rare congenital anomalies, occurring in less than 0.01% of the population. We report a rare case of bilateral hypoplasia of the ICA in a patient with post-traumatic subarachnoid hemorrhage. We describe the embryological development of the cerebral vasculature and present a review of literature.

Keywords

Agenesis - aortic arches - developmental anomaly - hypoplasia - internal carotid artery
