case_images: CT scan showing intussusception due to colon lipoma. Contrasted abdomen and pelvis CT. Axial (a), coronal (b, c), and sagittal (d) views show intussuscepted transverse colon (intussusceptum) with the mesenteric fat and vessels telescoped into the lumen of the descending colon (intussuscipiens) as shown in yellow arrows. The lead point is a lipoma (blue arrows), which is clearly demonstrated distally. Free fluid in the abdomen.

case_images: Her abdominal CT scan revealed a target sign at the descending colon suggestive of colo-colic intussusception measuring 11.6 x 5.2 x 5.3 cm with a lipoma measuring 3.7 x 4.3 x 3.5 cm as a lead point (Figure 1).
case_images: Photomicrographs showing colon lipoma histology. (a) Benign well-circumscribed colonic neoplasm composed of mature adipose tissue arising from submucosa with normal overlying mucosa. H&E stained low power (20x original magnification). (b) Histopathology of colonic lipoma. Intermediate magnification (40x original magnification).

case_images: Histology of the resected mass revealed a submucosal mass completely obstructing the large bowel lumen with microscopic features of reactive colon mucosa, a tumor composed of lobules of bland mature fat cells suggestive of a lipoma with negative margins (Figure 2).
case_images: Pre- and postoperative clinical photographs. (a) Clinical photograph after first laparotomy showing double-barrel transverse colostomy. (b) Post colostomy closure (second surgery).
