Cryptococcal meningitis in an immunocompetent patient

Abstract

Cryptococcal meningitis is a fungal infection that is most commonly thought of as an opportunistic infection affecting immunocompromised patients, classically patients with Human Immunodeficiency (HIV) infection. It is associated with a variety of complications including disseminated disease as well as neurologic complications including intracranial hypertension, cerebral infarcts, vision loss and other neurologic deficits. It is diagnosed by lumbar puncture with CSF studies, including fungal culture and cryptococcal antigen testing. We present a case of cryptococcal meningitis and fungemia in a previously healthy male patient who presented after multiple emergency department visits with persistent headache. After multiple visits, he underwent a lumbar puncture consistent with cryptococcal infection, and he was admitted to the hospital for initiation of antifungal therapy. His workup revealed no known underlying condition leading to immune compromise.
