Adult ileocolic intussusception caused by a terminal ileal lipoma: A case report

Figure 1 Abdominal computed tomography. A and B: Axial and coronal computed tomography (CT) images showing a well-circumscribed, oval-shaped mass (arrow) with homogeneous fat attenuation (approximately -53 Hounsfield units) within the ascending colon, pathognomonic for a lipoma, acting as the lead point for the intussusception; C: Axial CT image demonstrating the “target sign” (arrow), formed by the concentric rings of the edematous intussusceptum within the intussuscipiens; D: Coronal CT image showing the elongated intussuscepted bowel loop, known as the “sausage sign” (dashed arrow). HU: Hounsfield units.
