Patient Data

Age: 50 years

Very large, inflamed jejunal diverticulum in the left mid abdomen. Small oval enhancing collection along the medial aspect could be a small abscess or reactive inflammation of a separate diverticulum. Several other small, non inflamed diverticula along the mesenteric border of the jejunum. 

Right inguinal hernia with flat, fluid, and soft tissue thickening.

Case Discussion

The important thing when reading this case is not to call this an abscess. It is clearly communicating with the small bowel lumen, and upon closer inspection there are several other smaller non-inflamed jejunal diverticula along the mesenteric border. Thus it is important to be familiar with the appearance of small bowel diverticulitis, which I find often presents with much larger and more impressively inflamed diverticula than in the sigmoid colon, and that the diagnosis can be supported and confidently made when observing the presence of other non-inflamed small bowel diverticula.
