Figure 13: Intussusception. Intussusception is most frequently seen with polypoid adenocarcinomas of the cecum and ascending colon. (A and B) CT appearance of intussusception is distinct when imaged in cross section (arrows in Panel A) or longitudinally (arrows in Panel B). Panel C Intraoperative photograph shows that the intussusceptum follows the same path as the surgeon's finger. It drags with it the mesenteric fat, which accounts for the rings or bands of fat attenuation noted on the CT scans. Panel D Photograph of the gross specimen shows the polypoid cecal mass, which acted as a lead point (arrow), and extensive mucosal hemorrhage caused by ischemia due to intussusception.
