title: Small bowel intussusception due to a primary non-Hodgkin's lymphoma. An unusual presentation and clinical course.
abstract: OBJECTIVE
  Adult intussusception is a rare clinical entity accounting for 5% of all intussusceptions. Symptoms and signs are often vague and non-specific making a preoperative diagnosis difficult. The purpose of this study is to present a rare case of a jejuno-jejunal intussusception due to primary intestinal non-Hodgkin's lymphoma in a patient with an unusual clinical course.
  
  
  METHODS
  A 78-year-old man presented with a 1-month history of abdominal pain, nausea, epigastric fullness, and weight loss. Computed tomography scan and ultrasonography findings were suggestive of small bowel intussusception.
  
  
  RESULTS
  Laparotomy revealed a jejuno-jejunal intussusception caused by a primary B cell non-Hodgkin's lymphoma 20 cm distal to the ligament of Treitz. Resection without prior reduction was performed. The patient refused postoperative adjuvant chemotherapy. Seven months later, he presented with upper gastrointestinal bleeding, and the diagnostic evaluation revealed gastric infiltration of large B cell non-Hodgkin's lymphoma. Despite chemotherapy, he died of disseminated progressive disease 7 months later.
  
  
  CONCLUSIONS
  Adult jejuno-jejunal intussusception due to primary non-Hodgkin's lymphoma is a rare clinical entity. A high index of suspicion is needed as symptoms and signs are not pathognomonic. Appropriate investigations can lead to a prompt preoperative diagnosis. Resection without prior reduction is the treatment of choice. Our patient's refusal of postoperative adjuvant chemotherapy likely resulted in relapse of the disease in another part of the gastrointestinal tract.
