title: Ileo-ileal intussusception caused by diffuse large B-cell lymphoma of the ileum.
abstract: The occurrence of adult intussusception from small intestinal lymphoma is quite rare. We present an 82-year-old man with a two-month history of intermittent abdominal pain, nausea and fatigue. Clinical symptoms included moderate abdominal tenderness in the right lower abdomen. Computed tomography scan of the abdomen revealed a mass in the terminal ileum with the sign of "bowel within bowel" which was suspicious of ileo-ileum intussusception. The patient underwent laparoscopic segmental ileal resection. Pathologic evaluation revealed a diffuse large B cell non-Hodgkin's lymphoma of the ileum. The postoperative course was uneventful.
