A 74-year-old man with abdominal pain from the previous morning and admitted the following day was found in Abdominal X-ray to have an ileal obstruction pattern and, on computed tomography (CT), a double target sign with a central low-density area, indicating ileum-to-ileum intussesception. Surgical examination showed invagination 40cm oral to the terminal ileum. Upon manual reduction, a well-circum scribed pedicled tumor was palpated interminally, necessitating partial resection of the ileum and tumor. The resected specimen was a 7cm black polyp. Histological examination indicated Meckel's diverticulum accompanied by hemorrhagic necrosis. Ectopic pancreatic tissue was found in the diverticulum, classifying it as Heinrich II.
