ABSTRACT
Agenesis of the internal carotid artery is a rare congenital anomaly, occurring in less than 0.01% of the population. The patients with ICA agenesis are asymptomatic, sometimes discovered incidentally, or diagnosed by finding a collateral circulation .The most common type of collateral flow is through the Circle of Willis. The only method to the diagnosis of aplasia or agenesis of the ICA is based on angiographic findings and the presence of an absent or hypoplastic bony carotid canal by temporal bone CT. Carotid agenesis must be considered as a differential diagnosis while diagnosing many other clinical cases.
Key words: Agenesis, Carotid canal, Collateral circulation, Internal carotid artery.
