    Prospective series showing the importance of computerized stereotactic brain biopsy in the management of AIDS patients neurologically symptomatic and confirmed by images. Patients undergone an algorithm step by step done by their own doctors and referred to us for stereotactic biopsy. Our protocol was opened in August 1995 and closed in December 1996. Twenty patients were biopsied, This protocol is similar to the Levy's one (Chicago IL, USA). We have got diagnosis in all cases. Lymphoma was predominant and followed by toxoplasmosis, progressive multifocal leukoencephalopathy and HIV encephalopathy. We included one patient with diploic giant cells lymphoma. Our mortality and morbidity was zero. By these results we conclude that stereotactic biopsy in AIDS patients is safe and effective.

    (Assoc Arquivos De Neuro- Psiquiatria, 1998-06-01) Nasser, José Augusto [UNIFESP]; Confort, Carlos Ivam; Ferraz, Andrei; Esperança, José Carlos; Duarte, Francisco; Universidade Federal de São Paulo (UNIFESP); Universidade Federal do Rio de Janeiro (UFRJ)
    In a series of 44 image guided stereotactic biopsy from August 1995 until March 1997, findings were as follows (frequency order). Turners, glioblastoma. was the most frequent. Primary lymphoma and other conditions associated to AIDS. Metastasis, three cases. Vasculites, two cases. Arachnoid cyst, Creutzfeldt-Jakob, cortical degeneration, inespecific calcification tone case each). The age varied from 1 to 83 years. Forty one lesions were supratentorial, two infratentorial, and one was outside the brain (dura and skull) and we used stereotaxy to localize it. There was no mortality and morbidity was 2.3%. The literature is reviewed. We conclude that this procedure is safe and highly diagnostic.
