We report two cases of ileo-ileal intussusception due to a lymphoma in a 25-year-old and a leiomyoma in a 35-year-old woman. Both were diagnosed by laparotomy. Intussusception is a rare condition in adults and is usually difficult to diagnose. In contrast to childhood, idiopathic intussusception is quite rare in adults. The etiology is usually an intestinal tumor. In adults treatment is always surgical.
