FROM THE ARCHIVES OF THE AFIP - GASTROINTESTINAL MANIFESTATIONS OF ACQUIRED-IMMUNODEFICIENCY-SYNDROME - RADIOLOGIC-PATHOLOGICAL CORRELATION

Gastrointestinal diseases are common in patients with the acquired imm unodeficiency syndrome (AIDS), In this review, the radiologic and path ologic findings of these diseases in AIDS patients are illustrated wit h cases from the archives of the Armed Forces Institute of Pathology, Diseases are categorized in two etiologic groups, opportunistic infect ions and AIDS-related neoplasms, Opportunistic infections include thos e caused by viral, fungal, protozoan, and bacterial pathogens, The AID S-related neoplasms of primary importance are Kaposi sarcoma and non-H odgkin lymphoma. The radiologic findings of these gastrointestinal dis eases are frequently nonspecific, However, interpretation of the image s with knowledge of the underlying pathologic entities and the level o f compromise of the immune system helps narrow the differential diagno sis and often helps identify the presumptive diagnosis.
