title: Duodenal diverticula: potential complications and common imaging pitfalls.
abstract: A duodenal diverticulum is a commonly encountered entity in gastrointestinal radiology with a wide variety of appearances. The purpose of this review is to describe the normal anatomy and embryology of the duodenum, discuss the differences between a true versus intraluminal duodenal diverticulum, and to highlight the normal appearance, potential complications, and imaging pitfalls of duodenal diverticula.
