[Neurocysticercosis: report of an autochthonous case in Buenos Aires city].

Neurocysticercosis (NC) is a central nervous system disease caused by Cysticercus cellulosae, the larvae of Taenia solium. NC is found worldwide, and endemic in Latin America and Asia. In 1993, 11 adult patients with NC were reported in Buenos Aires, 8 from Bolivia and the rest from Argentina. Pediatric cases reported in Argentina have been from inner provinces or from rural areas. The purpose of the present article is to present the first autochthonous pediatric case, with local source of contagion in the city of Buenos Aires, and to alert regarding the possibility that the city become an endemic area, due to the migratory movements leading to establishment of asymptomatic carriers of Taenia solium in the urban area.
