ct

Concentric bowel wall soft tissue thickening over a 5.8 cm segment of the mid transverse colon is evident and is highly suspicious for colorectal carcinoma. Resultant short colo-colonic intussusception.

Several small adjacent nodules measuring up to 6 mm in diameter may reflect local metastases. No enlarged mesenteric lymph nodes identified.

Case Discussion

Adenocarcinoma confirmed at surgery.

Small bowel intussusception is often transient without a pathological lead point. Colonic intussusception however should always be regarded with suspicion.
