cytomegalovirus colitis

Cytomegalovirus (CMV) colitis is rarely reported in the immunocompetent adult and is often associated with inflammatory bowel disease (IBD), particularly ulcerative colitis (UC). An index of suspicion in the appropriate setting is vital to diagnosing the condition. Undiagnosed CMV colitis has a significant morbidity. A review of the natural history and diagnosis of CMV is followed by a discussion of the incidence, outcome and possible treatment of CMV in the immunocompetent patient.
