A 51-year-old woman presented to our clinic with a 1-year history of nonprogressive dysphagia for solids with no previous similar episodes. Physical examination was unremarkable. Gastrointestinal endoscopy revealed a pulsatile compression in the esophagus (Figure ). Computed tomography (CT) revealed an aberrant right subclavian artery on the left aorta and a Kommerell diverticulum resulting in esophageal compression (Figure ). We diagnosed dysphagia lusoria, provided the patient with lifestyle modification instructions, and referred her for the surgical removal of the aberrant artery and vascular reconstruction. At the patient's 3-month post-op follow-up appointment, she reported complete resolution of her symptoms.
