Fungal meningitis refers to meningitis caused by a fungal infection. Signs and symptoms
Symptoms of fungal meningitis are generally similar to those of other types of meningitis, and include: a fever, stiff neck, severe headache, photophobia (sensitivity to light), nausea and vomiting, and altered mental status (drowsiness or confusion). Causes
Fungal meningitis may be caused by the following (and also other) types of fungi:
Candida - C. albicans is the most common Candida species that causes infections of the central nervous system. Coccidioides - it is endemic to southwestern United States and Mexico. A third of patients presenting with disseminated coccidioidomycosis have developed meningitis. Histoplasma - occurs in bird and bat droppings and is endemic to parts of the United States, South, and Central America. Involvement of the central nervous system occurs in about 10-20% of cases of disseminated histoplasmosis. Blastomyces - occurs in soil rich in decaying organic matter in the Midwest United States. Meningitis is an unusual manifestation of blastomycosis and can be very difficult to diagnose. Cryptococcus (Cryptococcal meningitis) - it is thought to be acquired through inhalation of soil contaminated with bird droppings. C. neoformans is the most common pathogen to cause fungal meningitis. Aspergillus - Aspergillus infections account for 5% of fungal infections involving the central nervous system. Risk factors
Individuals with a weak immune system are most at risk. This includes individuals taking immunosuppressive medication, cancer patients, HIV patients, premature babies with very low birth weight, the elderly, etc.
