Cytomegalovirus pseudotumor

Cytomegalovirus (CMV) is a common pathogen affecting the gastrointestinal tract in patients with AIDS.

CMV-induced pseudotumor in patients with AIDS is an exceptionally rare clinical entity.

CMV pseudotumor should be included in the differential diagnosis of gastrointestinal mass lesions in AIDS patients and in other immunocompromised patients.

The tumor often responds to antiviral therapy, but resolution of a CMV mass as a result of oral antiviral therapy has not been previously described.

Since pseudotumors secondary to CMV often respond to medical treatment, it is important that the physicians treating severely immunocompromised patients are aware of this entity.
