Abstract
Infection with cytomegalovirus (CMV) is a major feature of acquired immunodeficiency syndrome (AIDS). Gastrointestinal involvement is being seen more frequently. Our collective experience involves nine patients with stomach involvement. Seven patients were intravenous drug abusers or homosexuals with AIDS. One developed CMV gastritis as a complication of leukemia and one patient was a West African with lymphoma and human immunodeficiency virus (HIV) infection. All our patients had biopsy-proven CMV inclusion bodies. The radiographic appearances varied widely. The findings included markedly thickened edematous folds, erosive gastritis with aphthous ulceration, and superficial and deep ulceration. One patient had deep ulceration with fistula formation. Computed tomographic (CT) scans confirmed the greatly thickened gastric wall and coarsened folds in two patients. Associated gastrointestinal infections included candida and herpes, and, in addition, pneumocystis carinii pneumonia (PCP) was present in two patients. CMV gastritis may mimic several other conditions including erosive gastritis, peptic ulceration, lymphoma, and carcinoma. It should be strongly considered in immunosuppressed patients.
