Anomalous origin and aneurysm of the right coronary artery associated with congenital bicuspid aortic valve: MDCT findings

Anomalous origin of the coronary artery taking an interarterial course can cause myocardial infarction or sudden death. Association of anomalous origin of the coronary artery with congenital bicuspid aortic valve is rare, and only a few cases have been reported with imaging findings. Coronary artery aneurysms found in young adults are usually non-atherosclerotic. We report MDCT findings of anomalous origin and aneurysm of the right coronary artery associated with congenital bicuspid aortic valve in a 33-year-old man with a history of Kawasaki disease in the childhood, and the key role of MDCT in exact diagnosis and successful management of the complicated disease.
