An unusual cause of chronic diarrhoea

A 47-year-old woman was admitted as an emergency with a 6 week history of colicky abdominal pain associated with loose stool and vomiting. Abdominal examination revealed tenderness on the right side of her abdomen and slight fullness on palpation. Computed tomography demonstrated intussusception. Right hemicolectomy was performed, and histology revealed low-grade B cell non-Hodgkins lymphoma. Intussusception is an infrequently encountered diagnosis in adults (5% of all intussuceptions) and 80–90 percent have a pathological lead point.
