An elderly man was admitted to hospital with dull abdominal pain and marked weight loss. Ileocolic intussusception was shown on colonoscopy and later confirmed at laparotomy. The main feature was a caecal lipoma. A review of the subject and comparison with two other cases is included in the report. If the colonoscopy reveals a coil-spring polypoid mass, intussusception must be considered as a diagnosis in patients with abdominal pain.
