“…If the IDD is distended with food and repetitive peristalsis extends to the distal duodenum or proximal jejunum, it may mimic intussusception. In some cases, IDD mimicking intussusception has been reported (3,4). In our case, the initial diagnostic impression was also duodenoduodenal intussusception.…”

“…Twenty-seven days post-admis- ings of IDD, and one report has described MRI findings of IDD (4,5,8). CT and MRI reveal both a fluid-filled sac within the duodenum, similar to the pathognomonic "windsock" appearance evidenced in classic barium studies (4,8). In particular, the T2-weighted MRI is useful for demonstrating fluid accumulation, surrounded by a hypointense rim, in the duodenum (8).…”

We present a case of IDD mimicking duodenoduodenal intussusception, diagnosed by computed tomography (CT) and gadoxetic acid-enhanced magnetic resonance imaging (MRI) without surgical correction. An initial contrast-enhanced CT, obtained at an outside institution, revealed an invagination of the second part of the duodenum, which continued into the fourth part (Fig. 1A). This "bowel-within-bowel" configuration was suggestive of intussusception. CASE REPORTFood materials were observed at the end of the intussusceptum, but no tumorous lesions were identified on the CT scan (Fig. 1B). A gadoxetic acid-enhanced MRI was performed to ascertain the cause of the duodenoduodenal intussusception. Follow-

“…The endoscopic findings are also characteristic in that the diverticulum appears as a blind pouch lined with normal duodenal mucosa. Intraluminal duodenal diverticulum has been reported (10,(12)(13)(14)(15)) in a few cases evaluated with computed tomography, endoscopic US, intravenous cholangiography, percutaneous transhepatic cholangiography, and endoscopic retrograde pancreatography.…”

“…At barium examination, such diverticula show the classic "windsock" deformity, with the contrast material-filled diverticulum seen to project into the true lumen. The diagnosis can also be made with CT, at which either a collapsed or contrast material-filled diverticulum can be seen (6).…”

Abdominal computed tomography (CT) is frequently performed to evaluate gastrointestinal pathologic conditions, and the majority of the gastrointestinal radiology literature has concentrated on the colon, stomach, and distal small bowel. In a description of CT findings of duodenal pathologic conditions, congenital, traumatic, inflammatory, and neoplastic diseases are presented. Congenital duodenal anomalies such as duplications and diverticula are usually asymptomatic, while annular pancreas and malrotation may manifest in the 1st decade of life. CT plays a vital role in the diagnosis of traumatic duodenal injury. Primary inflammatory processes of the duodenum such as ulcers and secondary involvement from pancreatitis can reliably be diagnosed at CT. Infectious diseases of the duodenum are difficult to diagnose, as the findings are not specific. While small bowel malignancies are relatively rare, lipoma, adenoma, and adenocarcinoma, as well as local extension from adjacent malignancies, can be diagnosed at CT. Careful CT technique and attention to the duodenum can result in reliable prospective diagnoses.
