Patient Data

Age: 50 years
Gender: Female

Duodenal enteroclysis


Images from a double contrast duodenal enteroclysis (note the post pyloric enteric tube on the first two images).

On the first six images -- the double contrast portion of the exam -- the polyp is partly lying in a small barium pool with the stalk partially visible. The margins of the polyp are etched with the barium. 

The last image is essentially a single contrast image and the polyp presents as filling defect in the barium pool.

Annotated image

The polyp is outlined in yellow.

Upper endoscopy


Photos of the polyp from an upper endoscopy. The polyp was subsequently snared and resected.

Case Discussion

This case shows a polyp on a duodenal enteroclysis, now an uncommonly performed type of gastrointestinal barium study.

This polyp turned out to be a duodenal hamartoma with focal gastric foveolar metaplasia; negative
for dysplasia.
