A Case of Pulmonary Cryptococcosis with Normal Immune Function

Objective Pulmonary cryptococcosis (PC) is a pulmonary fungal disease caused by Cryptococcus neoformans infection, the clinical manifestations are pneumonia or pulmonary nodules, or acute respiratory distress syndrome (ARDS) in severe cases. But its clinical manifestations lack specificity, so it is often misdiagnosed or missed in recent years. Pulmonary cryptococcosis is common in patients with human immunodeficiency virus (HIV) and non-HIV-associated immunosuppression, it has been found that pulmonary cryptococcosis is also common in people with sound immune function. The purpose of this paper is to report the diagnosis and treatment process of a patient with pulmonary cryptococcosis in our hospital, so as to provide reference for the diagnosis and treatment of the disease and reduce the misdiagnosis rate and missed diagnosis rate of the disease. Methods The diagnosis and treatment process of a case of pulmonary cryptococcosis in our hospital were reviewed. Results Combined with the patient's lung CT Imaging manifestations, and environmental exposure history and immune status, pulmonary cryptococcosis was considered. After empirical anti-cryptococcosis treatment, the patient's symptoms improved, and pulmonary nodules disappeared according to lung CT review. Conclusion Clinicians should identify the imaging characteristics of patients with cryptococcus pneumonicum and combine them with their environmental exposure history and immune status to avoid missed diagnosis and delayed disease.
