Gastric manifestations of AIDS: radiographic findings on upper gastrointestinal examination.

The radiographic findings in the stomach in the upper gastrointestinal examination in 11 patients with the Acquired Immune Deficiency Syndrome (AIDS) were reviewed. Four cases of Kaposi's sarcoma (KS) showed multiple submucosal nodular filling defects; in one of these cases, ulceration of some of the nodules was present. Gastric lymphoma occurred in two cases and appeared as one or several large nodular masses; one of these involved the esophagogastric junction. Five cases of infectious gastritis, caused by cytomegalovirus (CMV), Cryptosporidium, and Toxoplasma, were manifested as thickened gastric folds and/or antral narrowing. Thus, in patients with AIDS, gastric neoplastic lesions can be suggested when nodular filling defects or masses are identified, whereas inflammatory processes tend to show thickened gastric folds or antral narrowing. However, endoscopic biopsy is required to enable proper treatment.
