             Dysphagia lusoria is the medical term used to describe the co-occurrence of dysphagia in the setting of a congenital vascular anomaly causing extrinsic compression upon the esophagus, most commonly an aberrant right subclavian artery.  The majority of aberrant vasculature are incidental findings without associated symptoms, however those with symptoms may receive treatment in the form of conservative therapy and surgical correction if needed.  We present a complex case of a patient with aberrant right subclavian artery and bicarotid trunk causing dysphagia lusoria and dyspnea. The patient was diagnosed by esophagram and computed tomography angiogram, failed conservative management, and ultimately required surgical correction.  This case report focuses on the imaging and therapeutic options in these patients, as well as additional points to consider in the evaluation and management of patients with dysphagia lusoria.
