Abstract

A 61-year-old male with subacute headache was found to have cryptococcal meningitis despite a negative BioFire FilmArray meningitis/encephalitis panel. This case underscores the importance of liberal cryptococcal antigen testing, and that a negative FilmArray panel is inadequate in excluding cryptococcal meningitis, particularly in a HIV-negative host.
