A patient with AIDS and asymptomatic Chagas's disease and positive xenodiagnosis was taking ketoconazole in order to supress parasitemia and prevent reactivation of Chagas's disease. Ketoconazole was unplanned suspended after 6 months, and the patient was admitted with fever, headache, vomiting, tachycardia, postural hypotension, hepatosplenomegaly, and positive xenodiagnosis one month later. Treatment with benzonidazole was begun leading to supression of parasitemia. The patient had probabily a neurotoxoplasmosis associated and progressed to coma and death with sepsis. No parasite was found in autopsy.
