ABSTRACT

A case of Chagas' meningoencephalitis in a 47 year-old patient with AIDS is presented. The diagnosis was established by examination of the cerebrospinal fluid which showed the presence of Trypanosoma cruzi. CT-scan revealed multiple cerebral lesions which only became evident by contrast administration. A second CT after 13 days showed a severe evolution with displacement of the midline structures leading to the patient's death. This case, as well as other case reports published, has shown the fulminant evolution of Chagas'meningoencephalitis in AIDS patients and the importance of cerebrospinal fluid examination for the diagnosis.

ABSTRACT

A radiocirurgia consiste na irradiaçäo precisa de um volume alvo intracraniano com uma alta dose de energia, preservando o tecido nervoso adjacente. O desenvolvimento tecnológico dos aceleradores lineares, dos equipamentos estereotáxicos e da ciência de computaçäo simplificaram o procedimento e tornarom-no acessível. Suas indicaçöes principais säo as lesöes intracranianas inoperáveis como malformaçöes artério-venosa, schwnomas vestibulares e de outros nervos cranianos, meningeomas da base do crânio, gliomas e metástases cerebrais. Mais recentemente o desenvolvimento da radioterapia esterotáxica fracionada ampliou o espectro de indicaç 8es da radiocirurgia para lesöes maiores e adjacentes a estruturas nervosas críticas. Apresentamos a nossa experiência inicial com estas técnicas no tratamento de 31 pacientes. Observamos controle adequado das lesöes neoplásicas tratadas e aguardamos o tempo necessário para a observaçäo de resultados nas malformçöes artério-venosas
