ummary. Sixty HIV-positive patients admitted because of brain infection. Cryptococcosis, toxoplasmosis and tuberculosis were the main infectious processes. Twenty-eight cases had CT brain images. Causing organism of the neurological problems were verified by CSF-culture, CSF-PCR and serum titer. Every case showed a good response to the treatment. Fifteen patients had cryptococcosis; 60% showed normal pattern, 20% showed mild atrophy, 6.7% showed mild hydrocephalus, abnormal enhancement and enhanced nodule without surrounding edema. Eight cases were toxoplasmosis and all cases presented with multiple ring enhanced lesions with surrounding edema. Three cases had mixed infections of cryptococcosis and tuberculosis and showed normal pattern. One case of tuberculosis showed low density of white matter without nidus and another case showed infarction of the basal ganglia.
