Cryptococcal Meningitis Developing in a Patient with Neurosarcoidosis.

Abstract

Cryptococcal meningitis is a critical disease that occasionally involves immunosuppressed patients. We herein report a 79-year-old Japanese man who received low-dose prednisolone therapy for neurosarcoidosis and panhypopituitarism. He presented a 10-day history of a fever and altered mental status. The FilmArray® Meningitis/Encephalitis Panel and serum cryptococcal antigen tests were both negative, but the cerebrospinal fluid sample became positive for Cryptococcus neoformans after seven-day incubation. After the diagnosis of cryptococcal meningitis, we successfully treated the patient with a recommended treatment regimen. When an immunocompromised patient presents with a subacute fever accompanying any central nervous symptoms, cryptococcal meningitis should be screened for.
