OBJECTIVE
Cryptococcus neoformans, a common opportunistic pathogen among patients with human immunodeficiency virus (HIV) infection, lymphoproliferative disorders and other conditions causing immunosuppression, can be differentiated from other yeasts using biochemical tests as well as culture results and direct histopathological examination.
METHODS
We present a case of a 78-year-old man with Cryptococcal meningitis and false-negative cerebrospinal fluid culture results following receipt of capecitabine.
CONCLUSIONS
Patients receiving immunosuppressive agents are at higher risk of developing invasive fungal infections, and all patient medications should be reviewed to identify those with potential antifungal properties.
