A Mimic of Hepatic Encephalopathy: Two Cases of Cryptococcal Meningitis in North America

Abstract

In the non-human immunodeficiency virus infected population, cryptococcosis occurs primarily in people who are functionally immunosuppressed, including patients who have undergone solid organ transplantation requiring immunosuppressive medications, are on corticosteroids, or have renal failure or cirrhosis. Cryptococcal meningitis poses a particular challenge in the setting of cirrhosis because its clinical presentation can mimic hepatic encephalopathy. Here, we describe two patients with decompensated cirrhosis, both with a known history of hepatic encephalopathy who had lumbar punctures and were found to have cryptococcal meningitis. The first patient had a subacute fluctuating change in mental status, while the second patient had progressive subacute headaches, gait disturbance, and hearing loss. Both patients were treated with amphotericin B and flucytosine induction, but only the second survived to maintenance therapy. These cases demonstrate the importance of having a high index of suspicion for cryptococcal meningitis in cirrhosis and having a low threshold for performing a lumbar puncture when altered mental status or other neurologic complaints are not fully explained by hepatic encephalopathy. We also provide a brief review of the pathobiology of cryptococcal infection in cirrhosis and highlight the challenges in therapy.
