Abstract

Retrospective studies of 50 cases with eosinophilic meningoencephalitis who were admitted in Department of Medicine, Srinagarind Hospital during February 1984 to April 1987 were performed.  Age incidence was range from 15 years to 91 years, male to female ratio was 1.38 : 1. Most of them lived in Khn Kaen and nearby provinces.  There was no seasonal variation.  The main pressenting symptoms were severe headache and nausea/vomiting respectively.  Meningeal signs were found in 71.1%.  About half of them had history of eating uncooked snail and incubation period was ranged from 1 day to 30 days.  Abnormalities in cerebrospinal fluid were nonspecific.  Almost all of them was improved by lumbar puncture for releasing intracranial pressure and other supportive treatment.  Coma was the poor prognostic sign.
