Acute duodenitis following diagnostic upper gastrointestinal endoscopy. Axial unenhanced CT scan at the level of the third part of duodenum demonstrates extensive duodenal inflammation (white arrows) and periduodenal fat stranding. Compression of the inferior vena cava is also noted (black arrow).

A CT examination was performed on the fourth day after the UGI endoscopy to rule out potential complications, which demonstrated extensive duodenal inflammation without signs of perforation (Figures 1, 2).
Coronal reformatted CT image demonstrates duodenal thickening due to inflammation.

A CT examination was performed on the fourth day after the UGI endoscopy to rule out potential complications, which demonstrated extensive duodenal inflammation without signs of perforation (Figures 1, 2).
Axial unenhanced CT image of the lower part of the duodenum demonstrates a small amount of right paraduodenal fluid collection. The density of fluid collection indicates etiology other than hemorrhage.

The density of the paraduodenal fluid collection (8 HU) also diminished the possibility of hemorrhage (Figure 3).
Follow-up axial contrast enhanced CT scan reveals complete resolution of the findings.

A follow-up CT scan performed three days later demonstrated complete resolution of the findings (Figure 4).
Axial CT images of the same patient at different time points. Duodenal diverticulum (arrow) arising from the third portion of the duodenum is seen only in a single CT study (arrows in axial and reformatted unenhanced CT images) suggesting that duodenal diverticulum may not always be apparent on CT images.
