Congenital esophageal diverticulum

A rare, non-syndromic, congenital esophageal malformation characterized by a false diverticulum, most often located in the upper, posterior esophagus (pharyngo-esophageal) but may occur anywhere along the esophagus (mid-thoracic or epiphrenic). Many patients are asymptomatic, but bad breath, chronic cough, respiratory distress, food regurgitation, dysphagia, chest pain or discomfort, and aspiration pneumonia are typical presenting manifestations.
