Figure

  • Fig. 1. Abdominal and pelvic computed tomography (CT) scan. The coronal view CT scan reveals an intestinal intussusception with an intraluminal mass (arrow).

  • Fig. 2. The gross specimen and a schematic drawing of a hematoxylin and eosin (H&E)-stained slide. The tip of the pedunculated polypoid mass shows a mucosal ulcer (A, arrow) and mesenteric heterotopic pancreatic tissue (B, arrow). The entire image of the H&E slide (C) and its schematic diagram (D) reveal mesenteric heterotopic pancreatic tissue (D, light green area) and smooth muscle tissue (D, black area).

  • Fig. 3. Histologic features of the ectopic gastric mucosa and heterotopic pancreatic tissues. The inverted Meckel’s diverticulum contains ectopic, antral-type gastric tissues (A, arrow) and mesenteric, heterotopic tissues such as acinar (B, arrow), islet (B, star), duct (C, arrow), and smooth muscle bundle (D, arrow).
