Cryptococcus gattii meningitis complicated by immune reconstitution inflammatory syndrome in an apparent immunocompetent host in Malaysia.

Cryptococcosis is a systemic fungal infection caused by Cryptococcus neoformans or Cryptococcus gattii. Cryptococcus causes a wide range of diseases, ranging from asymptomatic pulmonary lesions to disseminated disease involving the central nervous system, particularly meningoencephalitis. C. gattii infection has rarely been reported in Malaysia. We present a case of C. gattii meningitis with pulmonary cryptococcosis complicated by immune reconstitution inflammatory syndrome in an apparently immunocompetent person with no prior travel history.
