A case of intussuscepted Meckel’s diverticulum

Figure 1 A polypoid lesion in the terminal ileum.

Figure 2 Contrast-enhanced abdominal CT showed massive invagination of long segmental ileal loops.

Figure 3 Macroscopically, a diverticular sac was noted along the antimesenteric border. The entire wall of both the diverticulum and intestine was affected by hemorrhagic infarction and the luminal surfaces were covered with a necrotic exudate.

Figure 4 Microscopically, the diverticular sac was totally involved in transmural infarction. Its wall had a continuous proper muscle layer and heterotopic gastric mucosa (Inset). (HE, × 40; inset × 200).
