[Jejuno-jejunal invagination in polypoid lipoma producing renal failure].

This is the case of a 43 years old woman with recurring epigastric pain for 8 years. She was hospitalized emergently for persistent vomiting causing acute renal failure. Numerous radiologic investigations prior to this hospitalisation showed no pathology. The diagnosis was made this time with a small bowel follow through. Intussusception of tumors is a known cause of small bowel obstruction. The clinical picture however, of severe vomiting causing acute renal failure on the basis of a proximal small bowel obstruction is exceptional.
