Cryptococcal Pleuritis in an Immunocompetent Patient: A Case Report and Literature Review

Cryptococcosis, primarily an opportunistic infection, often occurs in immunocompromised patients but can also affect immunocompetent individuals. Cryptococcosis typically manifests in the lungs, but pleurisy is rare, particularly in immunocompetent patients. This report details a case of cryptococcal pleuritis in a 74-year-old immunocompetent male with a history of heart failure, presenting initially with pleural effusion.
