A 74-year-old man underwent a CT examination for intermittent lower abdominal pain. The images revealed a tumor in the ileocecal region (Fig. 1A). Endoscopic examination showed the lesion to be a soft, yellowish submucosal tumor measuring 40 mm in diameter located in the terminal ileum (Fig. 1B). The lesion fully occupied the lumen; it moved to the cecum when pulled but immediately returned to the ileum upon insufflation (Fig. 1C). Based on CT and endoscopic findings, we made a diagnosis of lipoma.
