          Abstract

          Os espaços liquóricos foram estudados com SARI (soroalbumina radioiodada) em 25 pacientes. Para cada um foram realizados 3 mapeamentos num total de 75. Esses mapeamentos foram feitos 2, 6 e 24 horas após a injeção da SARI. Esta foi injetada no ventrículo lateral em 5 pacientes nos quais havia necessidade de estudar o sistema ventricular; na cisterna magna em 2, para estudo do espaço subaracnóideo intracraniano e intra-raqueano; nos outros 18 foi injetada por via lombar com a finalidade de estudar todo o canal raqueano. Os resultados obtidos pela cintilografia, comparados com aqueles fornecidos pelos exames neuroradiológicos, mostraram alto índice de positividade, tendo mesmo oferecido melhores informações em alguns deles. Isto se verifica principalmente nas aracnoidites. Nos processos expansivos do canal raqueano pode-se, com apenas uma injeção de SARI localizar o processo e determinar seus limites. Não se observou qualquer complicação grave. Em um caso verificou-se, no LCR, uma pleocitose sem sinais clínicos e em outro, um extravazamento da substância para o espaço peridural através do orifício de punção. Trata-se, pois, de método que oferece boa segurança para o diagnóstico neurológico, não provocando complicações temíveis.

          Translated abstract

          The ventricular system and subarachnoid spaces were studied with RIHSA (radioiodinated serum albumine) in 25 patients. A total of 75 scans were drawn; 3 on each patient. These scans were drawn 2, 6 and 24 hours after having administered RIHSA. The RIHSA was introduced into the lateral ventricle of 5 patients intended for the study of the ventricular system; into the cisterna magna of two patients, in order to study the intracranial and intraspinal subarachnoid spaces; in the other 18 patients it was injected by lumbar route for the study of the spinal canal. When the results obtained by the scintilography were compared with those shown by the orthodox neuroradiological methods the first ones showed high positivity, and even offered better information in some cases. This was especially true for the cases of arachnoiditis. It is possible to locate total or subtotal blocks of spinal canal as well as dmonstrate exactely its limits with only one intrathecal or cisternal introduction of RIHSA. No serious complications were observed. In one case o CSF pleocytosis developped without clinical symptoms; in another one, there was a leak of the substance through the puncture into the peridural space. This method offers high reliability in neurological diagnosis and does not produce serious complications.
