Kommerell diverticulum is a rare congenital anomaly of the aortic arch characterized by dilation at the proximal descending aorta, which gives rise to an aberrant subclavian artery. Kommerell diverticulum is usually asymptomatic, but can also be associated with symptoms due to compression of the esophagus or trachea, and can rarely be fatal due to dissection or rupture of the diverticulum. Here, we report a rare case of dysphagia caused by compression of the esophagus by Kommerell diverticulum originating from the right-sided aortic arch.
