Symptomatic CMV infection develops most commonly in organ transplant recipients and in individuals who receive immunosuppressive drugs, undergo haemodialysis or have acquired immunodeficiency syndrome. The link between ulcerative colitis and CMV infection and the efficacy of antiviral therapy in these individuals have been demonstrated. Due to the fact that synchronous onset of CMV and ulcerative colitis is a very rare clinical condition, we present here a synchronous-onset fulminant CMV and ulcerative colitis in a 58-year-old man without any other co-morbidities.
