case_images: The patient underwent colonoscopy (Fig. 1), which revealed a vegetative-infiltrative lesion, with irregular contours, hardened consistency, occupying about 75% of the lumen of the colon, located in the hepatic angle, presumably neoplastic.
case_images: A - CT scan, coronal section in portal phase: Intestinal invagination extending longitudinally by 20.7 cm. The segments involved present normal parietal enhancement by the iodinated contrast media. B - CT scan, sagittal section in portal venous phase: Head of the intussusceptum related to the fat densit, round formation, measuring 7.3 x 3.8 x 4.1 cm. C - CT scan, axial section in portal venous phase: Head of the intussusceptum related to the fat densit, round formation, measuring 7.3 x 3.8 x 4.1 cm.

case_images: Computed tomography scan (CT) of the abdomen revealed colo-colonic intussusception, with the descending colon being the intussusceptive element, and the transverse colon being the intussusceptum with collapsed walls (Fig. 2A). At the distal end of the transverse colon there was an oval formation, presenting fat density, corresponding to the head of the intussusception and suggesting lipoma or some of its histological variants (Fig. 2B and C).
