The spread of the acquired immunodeficiency syndrome, the increasing popularity of bone marrow, renal, and other organ transplants, and the development of potent immunosuppressive drugs have produced a large population of immunocompromised hosts. These patients are at great risk for developing both opportunistic infections and neoplasms such as Kaposi's sarcoma and lymphoma. The gastrointestinal complications and computed tomographic manifestations of these previously rare disorders are discussed.
