congenital esophageal diverticulum
Congenital esophageal diverticulum is a rare, non-syndromic malformation of the esophagus, present at birth, and characterized by a false diverticulum, most often located in the upper, posterior esophagus. Many patients are asymptomatic, but respiratory distress, food regurgitation, dysphagia, chest pain, aspiration pneumonia and discomfort are typical presenting manifestations.
