Esophageal compression by a mediastinal vascular structure as a result of a dysphagia lusoria.

Dysphagia lusoria is an uncommon cause of mechanical dysphagia due to extrinsic compression. It is a congenital aortic root abnormality that occurs as a consequence of an aberrant right subclavian artery, in most cases. We report an illustrative case of dysphagia lusoria in a young female, secondary to the presence of the abnormal mediastinal vessel.
