Cytomegalovirus (CMV) infection causes siginificant morbidty and mortality in immunopromised patients. Though it is usually silent in immunocompetent adults, rarely it can cause serious life-threatening complications. Gastrointestinal tract is one of the commonly involved organs, where it produces a spectrum of clinical manifestation ranging from mild non-specific abdominal pain and diarrhoea to severe infection with toxic megacolon and death. We present a 65-year-old immunocompetent male patient admitted with acute colonic obstruction secondary to CMV-induced colonic stricture, highlighting the importance of considering it as a differential diagnosis for colonic obstruction and reviewing its management.
