Mantle cell lymphoma as a rare cause of intussusception: a report of 2 cases

Intussusception is uncommon in adults and is only very rarely caused by malignant lymphoma. To our knowledge, there are only 2 previously reported cases of mantle cell lymphoma causing intussusception. We present 2 additional cases of intussusception at the ileocecal valve in patients being treated for mantle cell lymphoma, and a review of the pertinent literature is presented.
