Cytomegalovirus(CMV) infections are common in immune compromised situations such as human immunodeficiency virus infection and organ transplantation. However CMV colitis had been rarely found in immunocompetent individuals. We experienced a case of an 83-year-old female patient, initially immune competent, who developed a massive lower gastrointestinal bleeding caused by CMV colitis. Previously, multiple antibiotics were used for nontuberculous Myco- bacterium and other bacterial infections after total knee arthroplasty. Colonoscopy revealed multiple ulcerations and mucosal congestion with hemorrhage. In spite of ganciclovir therapy, our patient did not recover.
