Abstract:
A 24-year-old man returning from a trip to Mali was hospitalized for acute encephalitis and fever in association with acute primary infection by Schistosomiasis mansoni. Bilharziasis was suspected from the epidemiological context and presence of eosinophilia. Diagnosis was confirmed by serological testing. Specific treatment using praziquantel and corticotherapy was successful. Central nervous system involvement attributable to embolization of eggs or ectopic migration of adult worms has been reported in association with chronic Schistosomiasis by S. japonicum or S. mansoni. There have been few reports of acute neuroschistosomiais during the acute primary phase of infestation by S. mansoni. Etiology probably involves immunoallergic mechanisms.
