Jejunal Diverticulitis: A Rare Case of Severe Peritonitis.

A 25-year-old African American female with no prior medical/surgical history presented with abdominal pain and fever. A computed tomography scan of the abdomen and pelvis showed jejunal wall thickening with an air-fluid-filled mass in the adjacent mesentery. At laparotomy, a segmental jejunal resection with the abscess cavity followed by primary anastomosis was performed. Pathological evaluation of the specimen revealed a large mesenteric abscess contiguous with a perforated solitary jejunal diverticulum. We provide a discussion of jejunal diverticulitis as an unusual cause of peritonitis.
