Atypical Cryptococcal Pneumonia in an Immunocompetent Host: A Case Report and Review of Diagnostic and Therapeutic Challenges.

Cryptococcal infections, commonly associated with immunocompromised hosts, are rare but increasingly recognized in immunocompetent individuals. This case report describes a 39-year-old immunocompetent male presenting with cryptococcal pneumonia, initially misdiagnosed as bacterial pneumonia. The patient's persistent symptoms and diagnostic complexities highlight the importance of including cryptococcal infection in the differential diagnosis of chronic respiratory conditions unresponsive to conventional treatment. Treatment with fluconazole was effective, underscoring its role in managing isolated pulmonary cryptococcosis. This report aims to increase clinician awareness of the atypical presentations of cryptococcal infections in healthy hosts and the necessity of thorough diagnostic protocols for appropriate management.
