Disseminated Cryptococcal Disease in A Patient With Chronic Chylothorax and a Pleurovenous Catheter, a Case Report With Autopsy Findings.

Cryptococcus species are ubiquitous in the environment with a global distribution. While causing disease predominantly in immunocompromised hosts such as those with advanced HIV, HIV-uninfected patients are increasingly recognized as being affected. The most common forms of infection are cryptococcal pneumonia and meningitis. HIV-uninfected patients and extrapulmonary infections have worse outcomes, likely due to delayed diagnosis and treatment. Cryptococcus infections involving chylothorax or chyloabdomen have rarely been reported in humans. We describe a case of fulminant disseminated cryptococcosis with fungemia, peritonitis, and empyema in a patient with chronic chylothorax treated with an indwelling pleurovenous shunt. Key autopsy findings included cryptococcal organisms identified on calcified lymphadenopathy, pleural adhesions, and pericardium. We discuss the importance of identifying patients with nontraditional risks factors for cryptococcal disease, such as lymphopenia and hypogammaglobulinemia, and the potential implications of pleurovenous catheters in Cryptococcus dissemination.
