Multiple myelomatosis: an unusual cause of small bowel intussusception.

A 55 year old woman with multiple myeloma presented with a pathological fracture of the right neck of femur. Following internal fixation, and during subsequent radiotherapy, she developed small bowel obstruction. Laparotomy revealed an intussusception about a small bowel myeloma deposit. This is a previously unreported cause of small bowel intussusception.
