Eosinophilic meningitis: Report of three cases from a hilly area in Kerala

Abstract

Normal cerebrospinal fluid (CSF) does not contain eosinophils. The presence of >10 eosinophils/μL in CSF or at least 10% eosinophils in total CSF leukocyte count confirms eosinophilic meningitis. We present three patients with eosinophilic meningitis from the same locality with peripheral eosinophilia.
