Abstract
As immune checkpoint inhibitors (ICIs) are increasingly used, clinicians are more frequently encountering the side effects of these therapies. ICIs have been implicated in numerous adverse effects against healthy tissues. We present a case of a patient who developed treatment refractory checkpoint inhibitor colitis. Following colonoscopy, it was discovered that this patient had cytomegalovirus (CMV) coinfection. This case report highlights the importance of undertaking an appropriate assessment, including endoscopic and histologic investigation, of patients with presumed ICI colitis. Accurately diagnosing a superimposed CMV colitis changes clinical management and can improve patient outcomes.
