Frequency of suspected cases of neurocysticercosis detected by computed skull tomography in Santa Maria, RS, Brazil.

Due to the lack of studies about neurocysticercosis in the South of Brazil, an investigation was conducted to determine the percentage of suspected cases of neurocysticercosis in computed tomography diagnoses in Santa Maria, RS, from January 1997 to December 1998. Of 6300 computed tomographies (CT) of the skull performed at the private Hospital de Caridade Astrogildo de Azevedo, 80, i.e., 1.27% were suspected of neurocysticercosis. Fifty were women (62.5%) and 30 were men (37.5%). The most frequent radiological manifestation indicating neurocysticercosis was the presence of calcifications (isolated or associated), with a 95% rate (76 cases), while the presence of hypodense lesions reached a 5% rate (4 cases). After routine analysis, each CT was evaluated again and the suspected cases were confirmed. The percentage of suspected cases of neurocysticercosis detected by CT in the present study carried out in Santa Maria was considered low (1.27%). This can be explained by the fact that tomography is not accessible to the economically underprivileged population of Santa Maria. We hope that the present study can alert the population and the professionals to the fact that neurocysticercosis is a more frequent disease than indicated by the few diagnoses made.

Foram revistos os estudos radiologicos e ultra-sonogragicos de dez pacientes com pseudocisto do pancreas confirmados cirurgicamente. Todos eram do sexo masculino com antecedentes de alcoolismo e sinais clinicos de pancreatite.O resultado radiologico principal consistiu de massa opacificando o epigastrio e deslocando o estomago e alcas intestinais. Os exames ultra-sonograficos mostraram que as lesoes eram predominantemente cisticas, esfericas ou ovaladas, de contornos lisos, ou irregulares e tamanho variavel
