A right-sided aortic arch and Kommerell's diverticulum, remnants of the left dorsal aortic arch in the circulation of the embryo, are uncommon congenital defects of the aorta. They may be asymptomatic in most cases, but symptoms are manifested by compressing mediastinal structures or are related to congenital heart anomalies. If aneurismal dilatation of the diverticulum presents with rupture, it is lethal. We report a case of esophageal compression by a right-sided aortic arch and Kommerell's diverticulum that mimicked an esophageal submucosal tumor in a patient who complained of symptoms during the past ten years of food retention in the upper thorax when a bolus of food was ingested.
