Abstract

Cryptococcal meningitis is an opportunistic infection predominantly affecting immunocompromised patients but rarely can affect the immunocompetent. We describe a 53-year-old Caucasian man who presented complaining of a 2-week history of severe bilateral eye pain and diplopia. His only known risk factor was that he lived in a horse farm and recently shot bats and pigeons in his barn. He visited an outside hospital during this time without a diagnosis established. After further deliberation, we obtained a lumbar puncture (LP) which revealed an opening pressure (OP) of 27 cm H₂O. Cerebrospinal fluid (CSF) and fungal cultures confirmed the presence of Cryptococcus neoformans. The patient was diagnosed with C. neoformans-mediated meningoencephalitis and was initiated on the appropriate induction anti-fungal therapy. This case emphasises the need for clinicians to remain vigilant and consider cryptococcal meningitis in immunocompetent individuals even when classic symptoms of meningitis are absent.
