Short segment circumferential thickening of the sigmoid colon, with diverticula seen within this segment. Narrowing means that the fold pattern is not clearly seen. Relatively shouldered distal edge. Minimal fat stranding but no adjacent peritoneal thickening and no free fluid. Some tissue extends to the superior bladder wall but there is no intraluminal gas to indicate an established fistula. Multiple small nodes in the adjacent fat. No signs of colonic obstruction. No perforation. No suspicious liver lesion. Small right lower lung nodule unchanged over many years, with no suspicious lung nodules seen.
There are mixed signs of both diverticular disease and malignancy here, but on balance due to the preservation of diverticula this was felt to be benign disease. Nonetheless, due to symptoms, the patient underwent surgery.
