Duodenal lipoma

Case contributed by Henry Knipe
Diagnosis almost certain



Patient Data

Age: 80 years
Gender: Male

Within the first part of the duodenum is a fat-density mass. 

Bilateral non-obstructive renal calculi. Left simple renal cysts. Bladder calculi. Prostatomegaly. 

Colonic diverticular disease. Umbilical hernia containing omental fat. 

Case Discussion

When fat-density masses are seen in the bowel are usually pseudomasses of food. In this case, the fat-density duodenal mass was present on a prior scan from six months prior and unchanged in position. Duodenal lipomas are rare benign tumors that can present with upper gastrointestinal bleeding, abdominal pain, intussusception, and/or gastric outlet obstruction, although in this case, the finding was incidental.
