Right aortic arch and the aberrant origin of the left subclavian artery, which passes anterior to the esophagus, is dilated (Diverticulum of Kommerell).

Case Discussion

A Kommerell diverticulum 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.
