Interrupted aortic arch anomaly (IAA) characterized by complete luminal dissociation between the ascending and descending aorta and accounting for less than 1% of all cases of congenital heart disease. IAA is a rare condition in infants that occurs approximately three times per million births. It is usually diagnosed and repaired during the neonatal period and is extremely rare in adults. We present the case of an adult man who was diagnosed with IAA accompanied by intracranial aneurysms causing subarachnoid hemorrhage and demonstrate the imaging findings with 256-slice computed tomography angiography and digital subtraction angiography.
