Typically presents as a progressive, life-threatening, chronic or subacute meningitis.
Occurs most commonly in immunosuppressed individuals and is often accompanied by systemic involvement.
Cerebrospinal fluid (CSF) typically shows lymphocytic pleocytosis, elevated protein, and low glucose.
The most common type of fungal meningitis is caused by Cryptococcus neoformans .
A rapid aetiological diagnosis is required to guide antifungal therapy.
Complications include seizures, cerebral infarction, hydrocephalus, and elevated CSF pressure without hydrocephalus.
Meningitis is an inflammatory disease of the leptomeninges. All major fungal pathogens have the capacity to cause meningitis. The incidence of fungal meningitis is increasing worldwide due to the increasing number of patients immunosuppressed by pharmacological agents and HIV infection. Cryptococcal, histoplasmal, coccidioidal, and candidal meningitis will be discussed specifically in this monograph.
