Aberrant right retro-esophageal right subclavian artery with Kommerell diverticulum. Normal appearance and caliber of the thoracic aorta with no evidence of dissection. Mild atherosclerotic disease.

Case Discussion

Kommerell diverticulum usually refers to the bulbous configuration of the origin of an aberrant left subclavian artery in the setting of a right sided aortic arch. However, it was originally described as a diverticular outpouching at the origin of an aberrant right subclavian artery with a left sided aortic arch as in this case.
