Cytomegalovirus (CMV) rarely causes gastritis; its prevalence among CMV patients is unknown. [2] CMV gastritis is usually, but not always, encountered in individuals who are immunocompromised, including those with cancer, on immunosuppression medications, after transplants, and AIDS. Yamamoto and Sakai described a case of gastritis due to concurrent infection with Epstein-Barr virus (EBV) and CMV in an immunocompetent adult. [3] Gastric involvement can be localized or diffuse. CMV gastritis is essentially diagnosed by gastroscopy and biopsy because viral load and immunoglobulin (Ig) M level could be misleading. [2]
