[Three-year survival of a patient with HIV and chagasic meningoencephalitis: case report].

Immunocompromised patients as those with renal transplant, hematological neoplasia or cancer and HIV/AIDS infection can suffer acute reactivation of Chagas disease. Central nervous system (CNS) evolvement (cerebral tumor or chagoma and diffuse meningoencephalitis) is similar to other opportunistic infections that present with cerebral expansive processes like toxoplasmosis or CNS primary lymphoma. Survival is infrequent, depending on antiparasitic therapy and early starting antiretroviral therapy. The case of an HIV/AIDS positive patient that evolved with a chagasic meningoencephalitis and improved after beginning early antiparasitic therapy and antiretroviral therapy antiretroviral is described.
