Hydrocephalus in Coccidioidal Meningitis: Case Report and Review of the Literature

Abstract

Coccidioidomycosis should be considered in the differential diagnosis of occult basilar meningitis. The diagnosis is established by the discovery of a high (>1:2) titer of complement-fixing antibody in the cerebrospinal fluid. Communicating hydrocephalus is a common complication of untreated coccidioidal meningitis, and it may develop during appropriate treatment (oral fluconazole, 200-400 mg/d, continued indefinitely). Patients with hydrocephalus and evidence of increased intracranial pressure require a shunt.
