摘      要：Azygos anterior cerebral artery (ACA) is type I variation of ACA with a reported incidence of 1% in population(1)This variation predisposes to the formation of aneurysm especially at the bifurcation zone. The aneurysm develops because of double hemodynamic pressure supplying medial surface of both cerebral hemispheres. However reported incidence of saccular aneurysm in azygos ACA is between 13% and 71%(2,3)It is often associated with other central nervous system (CNS) malformations like agenesis of corpus callosum, hydranencephaly and other vascular malformations[4].
