title: Aortic diverticulum without vascular ring: a rare cause of dysphagia.
abstract: In an adult with severe dysphagia, diagnosis of aneurysmal aberrant subclavian artery was suspected on computed tomogram; no vascular ring was visible on arteriogram. A diverticulum of the aortic isthmus was surgically resected. Histologic analysis ruled out acquired disease. In conclusion, dysphagia related to esophageal compression may be caused by an isolated congenital aortic diverticulum.
