## Abstract

Intraluminal duodenal diverticulum (IDD) is an exceedingly rare congenital anomaly of the foregut. This entity is most frequently discovered incidentally during esophagogastroduodenoscopy; however, patients have reported symptoms of gastrointestinal obstruction, bleeding, or pancreatitis. In this report, we discuss a case of an IDD that was diagnosed during routine upper endoscopy in an adult woman who was referred to the gastroenterology clinic because of unexplained changes in her bowel habits.
