Crystal-Induced Lower GI Necrosis in a Posttransplant Recipient with Diverticular Disease

We report the case of a 67-year-old male kidney transplant recipient for 12 years with sodium polystyrene sulfonate crystal-induced ileocecal colitis. He had adult polycystic kidney disease with associated colonic diverticular disease. Here, we describe how a potentially fatal complication of colonic perforation was averted with appropriate investigations and management.
