A 47-year-old man suffering from abdominal pain and vomiting had been admitted a third time for the same symptoms, but previously treated conservatively. Based on abdominal computed tomography and hypotonic duodenography, we diagnosed obstruction of the jejunum due to an internal hernia in the Treitz ligament and conducted a laparotomy. We found that the jejunum, 6 cm distal to the Treitz ligament adhered to the retroperitonium, forming a diverticulum. We conducted wedge resection and the postoperative course was uneventful. Histopathological examination of the diverticulum showed a true diverticulum of the jejunum with an inflammatory change at the serosa but not at the mucosa site. The definitive diagnosis was traction jejunal diverticulosis, making this case one of interest due to its rarity.
