A rare case of chronic intussusception due to non Hodgkin lymphoma.

ABSTRACT

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 intussusception due to Non Hodgkin lymphoma of ileum, appendix, caecum and ascending colon presented as acute intestinal obstruction 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 investigations (USS, Barium enema and CT scan) can result in prompt diagnosis. In majority of children the diagnosis is made at laparotomy and surgery plays a pivotal role in the management.
