There is marked fat stranding in the right lower quadrant. While both the cecum and the appendix appear involved, the inflammation appears centered around a hyperdense cecal diverticulum. This is a surgically proven case of cecal diverticulitis. Changes in the appendix are reactive to the primary process within the cecum. Surgical exploration revealed an inflamed and edematous cecum with intramural abscess. Ileocecectomy was successfully performed.
