Abstract
Cytomegalovirus colitis in immunocompetent patients has rarely been reported without another severe illness. The prognosis is usually bad, leading to toxic megacolon or death due to multi-organ system failure. We report a case of a self-limited cytomegalovirus colitis in a young patient with no risk factor for CMV infection or associated disease. This suggests that self-limiting CMV colitis may be more frequent than is usually believed, and its prognosis may be better in young patients with normal immune functions. Therefore it should be sought systematically even in immunocompetent young patients.
