Intraventricular neurocysticercosis.

Neurocysticercosis is the commonest CNS parasitic disease worldwide but cysticercal meningitis and intraventricular lesions are relatively rare, especially in Indian patients. We herein report a girl with cysticercal meningitis that remained undiagnosed and the patient later presented with unilateral hydrocephalous due to Foramen of Monroe block by an intraventricular cyst. The need for CSF examination with Wright-Giemsa staining to avoid missing CSF eosinophilia is discussed.
