At the hepatic flexure, there is colo-colonic intussusception. At the lead point of the intussusceptum there is a heterogeneous mass. No upstream colonic or small bowel dilatation.
The remainder of the abdomen is unremarkable. No osseous or lung bases metastases demonstrated.
Conclusion:
Hepatic flexure mass, compatible with carcinoma, acting as a lead point for colo-colonic intussusception.
