A rare case of chronic intussusception due to Non Hodgkin lymphoma

Chronic intussusception is defined as intussusception with a history of more than 14 days and is generally associated with a predisposing factor. We are reporting a rare case of chronic intus- susception due to Non Hodgkin lymphoma of ileum, appendix, caecum and ascending colon presented as acute intestinal obstruc- tion in emergency. Chronic Intussusception is rare in childhood due to Non Hodgkin lymphoma. A five year male child presented with fever, pain abdomen, vomiting, diarrhoea and mass in right flank. Ultrasonography of the abdomen revealed a mass in ileao-caecal region with chronic intussusception which was confirmed on surgery. X ray of the abdomen showed dilated bowel loops. It is very difficult to make diagnosis of intestinal lymphoma on pre-operative investigations. Patient presented with obstruction should be explored as surgery is the treatment of the choice. Diagnosis can be confirmed by histopathologically. In conclusion, a high index of suspicion and appropriate investi- gations (Uss, Barium enema and CT scan) can result in prompt diagnosis. In majority of children the diagnosis is made at laparo- tomy and surgery plays a pivotal role in the management. (Acta gastroenterol. belg., 2012, 75, 42-44).
