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.
Core tip: Intussusception is a common cause of bowel obstruction in pediatric patients. Primary diffuse large B cell non-Hodgkin’s lymphoma of the small intestine is rare. Intussusception due to primary diffuse large B cell non-Hodgkin’s lymphoma in the small intestine is even rarer in adults and is often difficult to diagnose. This article describes the diagnosis and management of this rare disease.
