Left Internal Carotid Artery Agenesis in a Child

Abstract

ABSTRACT:Internal carotid artery (ICA) agenesis is a rare congenital anomaly. Most of the patients remain asymptomatic due to collateral blood flow and are discovered incidentally. Increased incidence of intracranial vascular anomalies are associated with ICA agenesis. We report a symptomatic case of ICA agenesis in a child with collateral supply from basilar artery.
