Abstract
Gastric heterotopia rarely occurs in the ileum without a Meckel's diverticulum. We report a case of a 53-year-old man who presented with recurrent abdominal pain. The initial computed tomography (CT) scan showed circumferential wall thickening and stricture of the ileum. At the follow-up examination (8 months), previously observed circumferential wall thickening and stricture were more aggravated, causing small bowel obstruction. The patient underwent small bowel resection and the histopathology was consistent with ectopic gastric mucosa. We suggest that the rare CT findings were indicative of ileal gastric heterotopia which have never been reported. Based on these CT findings, our differential diagnosis excluded inflammatory bowel disease.
