Acute intestinal intussusception in adults is a rare condition, most often secondary to an organic lesion (tumor or inflammation), representing 1%-5% of intestinal obstructions. Pure colic intussusception on lipoma rectal causing bowel obstruction is an exceptional situation. A 60-year-old man presented to the emergency department for acute abdominal pain with marked abdominal distention and red rectal bleeding. A contrast-enhanced abdominal CT scan was performed, which revealed a recto-sigmoid intussusception on lipoma, causing mechanical intestinal obstruction. The patient underwent a partial reduction of the intussusception with partial sigmoid resection and end colostomy. Colonic lipomas of the recto-sigmoid region represent a very rare condition and a subsequent etiology for intussusception and bowel obstruction in adults. However, it should be considered in the differential diagnosis of such situations.
