Abstract:
A case of gastric outlet obstruction accompanied by diffuse gastritis and gastric ulcer due to cytomegalovirus infection is presented. The patient, a woman aged 67 years with a long history of rheumatoid arthritis under immunosuppressive treatment (methotrexate), was admitted to our department complaining mostly of abdominal pain located in the epigastrium and the right abdomen. Upper gastrointestinal endoscopy revealed the presence of gastritis accompanied by ulcer in the prepyloric area and gastric outlet obstruction due to cytomegalovirus infection which was confirmed histologically. The patient responded well - although after many weeks - to specific treatment with antiviral treatment (ganciclovir). It is concluded that gastric outlet obstruction caused by cytomegalovirus infection can be observed in immunocompromised patients. The clinician must search for possible cytomegalovirus infection in all immunocompromised patients presenting with a clinical picture of gastric outlet obstruction by obtaining enough biopsies and by asking the histopathologist to specifically stain the specimen for the presence of cytomegalovirus, especially if infection by Helicobacter pylori is not present.
