Acute cysticercal meningitis--missed diagnosis.

Neurocysticercosis is the commonest CNS parasitic disease worldwide but cysticercal meningoencephalitis is relatively rare, especially in Indian patients. We herein report a girl with cysticercal meningitis that was initially not suspected and later diagnosed on the basis of cerebrospinal fluid (CSF) eosinophilia. The need for CSF examination with wright-giemsa staining to avoid missing CSF eosinophilia is discussed.
