True or false? The most common cause of benign colonic intussusception are colonic lipomas.
Colonic lipomas are by far the most common *benign* cause for a a colonic intussusception.
Large ovoid intraluminal fatty lesion in the proximal transverse colon, resulting in ascending colocolic and ileocolic intussusception. This lesion demonstrates internal septal enhancement after the administration of intravenous contrast, with no definite enhancing soft-tissue components.
A delayed prone scan obtained with rectal contrast revealed good luminal opacification of the left hemicolon and clearly delineates the leading point of intussusception. No signs of large bowel obstruction.
The ascending and proximal transverse colonic walls appear to be burdened by extensive diverticular disease, likely secondary to chronic increased intraluminal pressure and constipation. No signs of acute diverticulitis.
No suspicious enhancing colonic wall lesions.
Extensive reactive mesenteric lymphadenopathy in the right iliac fossa, associated with a small amount of surrounding fat stranding. No free fluid or localized collections.
