A revision of literature was done with the objective of tracing an epidemiologic profile of neurocysticercosis (NCC) in Brazil. The prevalence was 0.12-9% in autopsies. The frequency was 0.03-7.5% in clinical series and 0.68-5.2% in seroepidemiological studies. The disease corresponds to 0.08-2.5% of admissions to general hospitals. Patient origin was rural in 30-63% of cases. The most involved age range (64-100%) was 11 to 60 years, with a predominance (22-67%) between 21 and 40 years. The male sex was the most affected (51-80%). In the severe forms there was a predominance of urban origin (53-62%) and of the female sex (53-75%). The period of hospitalization ranges from 1 to 254 days and 33 to 50% of patients suffer 1.7 ± 1.4 admissions. The clinical picture was variable, with a predominance of epileptic syndrome (22-92%) and intracranial hypertension (19-89%). Psychiatric manifestations were associated in 9-23% of patients. Lethality was 0.29% in terms of all diseases in general and 4.8-25.9% in terms of neurologic diseases. The asymptomatic form was detected in 6% of patients in clinical serie and in 48.5% of case from autopsies. The racemose form and ventricular localization also was observed as asymptomatic form. Among the patients with cutaneous cysticercosis 65% of them showed neurologic manifestations.

A freqüência, nas casuísticas clínicas foi de 0,03-7,5% e, nos estudos soroepidemiológicos, de 0,68-5,2%. Compreendeu 0,08-2,5% das internações em hospitais gerais. A procedência foi rural em 30-63% dos doentes. Comprometeu mais (64-100%) na faixa etária dos 11 aos 60 anos, predominantemente (22-67%) entre 21 e 40 anos. O sexo masculino foi mais atingido (51-80%). Nas formas graves, houve predomínio da origem urbana (53-62%) e do sexo feminino (53-75%). O período de internação variou de 1 -254 dias, com 33 a 50% dos doentes necessitando ...
