We describe a case of heterotopic pancreas of the ileum causing ileus. A 76-year-old woman operated on for p-StageIB adenocarcinoma of the left lung and admitted with abdominal pain and vomiting was found in abdominal US, CT, and a small intestinal series to have ileal obstruction whose etiology was obscure. Intubation with an intestinal tube resolved symptoms, but the ileus recurred after extubation. Exploratory surgery found the ileum 150 cm orally from the ileocecal valve to be stenotic cicatricially, and the lesion was resected segmentally, Histopathological examination of the lesion showed heterotopic pancreatic tissue, Heinrich type I. It was difficult to obtain a definite diagnosis of heterotopic pancreas, and it was necessary to consider the lung cancer metastasis to the small intestine. This rare abnormality of the ileum is thus difficult to diagnose.
