Rare presentation of ileocolic intussusception secondary to mantle cell lymphoma

Abstract

Mantle cell lymphoma is a type of B-cell non-Hodgkin's lymphoma (NHL) and accounts for 3%-6% of all adult NHL. 1 2 Bowel intussusception secondary to lymphoma is rare in adults, accounting for only 4% of all cases. 3 The authors present the case of a 53-year-old man, recently diagnosed with mantle cell lymphoma, who presented with sudden onset right-sided abdominal pain and was found to have ileocolic intussusception up to the hepatic flexure on abdominal CT. He underwent an emergency right hemicolectomy and intraoperatively, the terminal ileum could be seen telescoping into the caecum, up to the hepatic flexure. Although intussusception is uncommon in the adult population, an underlying bowel pathology should always be considered and prompt imaging should be organised to confirm the diagnosis and allow initiation of management in a timely manner.
