Infection with gastrointestinal cytomegalovirus in an immunocompetent host is a rather rare occurrence in the literature. There are a few reports of gastrointestinal infection in the immunocompetent who are then subsequently given a new diagnosis of inflammatory bowel disease. It is speculated that the initial cytomegalovirus colitis infection triggers the onset of inflammatory bowel disease.
CASE REPORT: Herein we report a case of cytomegalovirus colitis and new diagnosis of inflammatory bowel disease identified in a 40-year-old immunocompetent adult man who presented with gastrointestinal symptoms and disseminated cytomegalovirus infection requiring anti-viral therapy, which successfully treated the episode of cytomegalovirus infection. He then went on to have persistent symptomatic inflammatory bowel disease confirmed by pathology.
CONCLUSIONS: In this paper we will review the literature and explore the rare case of cytomegalovirus colitis in the immunocompetent host and discuss the pathology, physiology, diagnosis, and treatment of cytomegalovirus colitis.
