A 49-year-old man was incidentally found to have a right-sided descending thoracic aorta and multidetector computed tomography was performed. There was a right aortic arch with separate arch branches arising in the following order: left common carotid artery (Lt.CCA), right common carotid artery (Rt.CCA), right subclavian artery (Rt.SA), and left subclavian artery (Lt.SA), which was aberrant, all arising from a Kommerell diverticulum (KD) (1) and passing through the dorsal side of the trachea and esophagus. His coronary arteries had the dominant left circumflex artery and the hypoplastic right coronary artery. This anomaly is explained by atresia of left aortic arch between left carotid artery and left subclavian arteries in Edward's hypothetical double aortic arch (2) (type E). The left panelis a front view and the right panelis a back view. Separate arch branches and KD were recognized by these images. CRT = cranial; LAO = left anterior oblique.
