Dysphagia Lusoria and Zenker`s Diverticulum

Abstract

An 81-year-old woman was referred for evaluation of dysphagia which she had suffered for four years. An upper gastrointestinal endoscopy revealed a Zenkers diverticulum and extrinsic compression of the esophagus. A thoracic CT scan conrmed the presence of extrinsic compression caused by an aberrant right subclavian artery, which compromised the posterior esophageal wall thus conrming a diagnosis of dysphagia lusoria. An association between Zenkers diverticulum and dysphagia lusoria is so uncommon that there have been no previously published cases.
