AIDS and Chagas' disease

Chagas' disease can reactivate in patients with AIDS and present as a brain mass lesion or an acute diffuse meningoencephalitis indistinguishable from other opportunistic infections or neoplastic processes, such as toxoplasma encephalitis or central nervous system (CNS) primary lymphoma. The CNS tum or-like lesion is the most common manifestation of Chagas' disease reactiva tion in AIDS patients. The prognosis of untreated cases is grim and undersc ore the need for safe and effective therapeutic agents.
