We experienced intraluminal doudenal diverticulum (IDD) with the ampulla of Vater inside it. A 47-year-old man was admitted to our hospital complaining of epigastralgia. Abdominal ultrasonography and computed tomography revealed a cystic mass that showed mobility. Hypotonic duodenography and endoscopic examination revealed an elevated lesion with smooth surface in the second portion of the duodenum. At laparotomy there was a cystic mass with orifice at the anal side of its surface. We performed simple excision of the mass at its base. Histological examination of the excised specimen revealed normal duodenal mucosa on each side and the lack of proprial muscle; therefore it was diagnosed as IDD.
