Benign duodenal stricture

Contributed by: Ed Boas

Clinical history: 64 year old man presents with reflux.

Findings:

Upper GI series shows a duodenal stricture.  No mucusal irregularity.

CT shows the duodenal stricture with no associated mass.  There is submucosal fat.

Discussion:

Submucosal fat can be seen with chronic inflammation (such as Crohn's disease, although there were no other imaging findings to suggest Crohn's).  Findings are consistent with a benign stricture.

Biopsy of the duodenal stricture showed chronic duodenitis.  The patient had a history of chronic NSAID use.  This is presumably a NSAID-induced stricture.
