Cytomegalovirus-Related Gastritis in an Immunocompetent Host Presenting With Infectious Gastroparesis.

Cytomegalovirus (CMV) infection is usually asymptomatic or causes a mild mononucleosis-like syndrome, whereas severe symptoms are rarely reported. We report a case of a 70-year-old woman who was admitted to our center because of severe clinical presentation with anorexia, epigastric pain, nausea, postprandial vomiting, and significant weight loss. Esophagogastroduodenoscopy with biopsies showed ulcerative chronic gastritis with scattered large cells with inclusion bodies. Immunohistochemistry and polymerase chain reaction for CMV-DNA resulted positive. A gastric emptying of solid scintigraphy showed severe gastroparesis. The patient was discharged after 2 months of antiviral therapy completely asymptomatic. To the best of our knowledge, this is the first case of CMV-related gastroparesis in an immunocompetent patient, successfully treated with antiviral therapy.
