Cerebral cysticercosis in Campina Grande, Paraíba--northern Brazil. Computerized tomography diagnosis importance.

Neurocysticercosis is the infection of the central nervous system by the larval form of Taenia solium, the Cysticercus cellulosae. We studied 4011 computerized tomographies performed in TomoHPI Radioimaging Service, Hospital Pedro I, Campina Grande PB, Northern Brazil, since its installation on August 1993 to July 1995. 41 patients were diagnosed as having Cysticercus cerebral infestation, corresponding to an incidence of 1.02%. No cases were related in Campina Grande PB during 1991 according to hospitalizations under prospective payment rates. After this radioimaging service installation, we observed 1.86 cases per month. We conclude that Campina Grande has to be included as an endemic area of neurocysticercosis, needing health service measures to cease the cycle Taenia-Cysticercus, the only way to get rid of such a serious problem.
