Abstract
Cytomegalovirus is one of the more common opportunistic organisms implicated in the development of esophagitis in patients with AIDS. A review of the radiographic features of 16 proved cases of cytomegalovirus esophagitis showed a spectrum of abnormalities related to the severity of the inflammatory process. Seven patients had a mild form of esophagitis with segmental involvement characterized by granular mucosa, superficial erosions, and poorly defined, shallow ulcerations. Nine patients had more severe esophagitis with solitary or multiple deep ulcers and a background of normal mucosa. The deep ulcerations were oval in shape and varied in size. Some projected intraluminally and had a thin rim of radiolucency at the base. Short-term follow-up examinations showed progression of the disease in four patients, no change in one patient, and regression without specific therapy in one patient. Although these radiographic features are highly suggestive of cytomegalovirus esophagitis, the diagnosis requires histologic confirmation.
