The gastrointestinal manifestations of pediatric AIDS.

The manifestations of AIDS in the gastrointestinal tract in children are mainly secondary to opportunistic infections and AIDS-related neoplasms. This article reviews the radiologic and pathologic findings seen throughout the gastrointestinal tract and within the abdomen in children afflicted with AIDS. Although many radiologic findings are not specific for a particular infection or neoplasm, the radiologist can narrow the differential diagnosis with a good knowledge of the imaging findings and pathologies specific for children with AIDS.
