Clinical Report: Cavitary Pulmonary Cryptococcosis in an Immunocompetent Pediatric Patient
Overview
This report details a case of pulmonary cryptococcosis in a 14-year-old girl with normal immune function.
Background
Pulmonary cryptococcosis (PC) is recognized in immunocompetent patients, with non-specific symptoms leading to potential misdiagnosis.
Data Highlights
The patient was treated with oral fluconazole. Follow-up imaging indicated resolution of the pulmonary lesion.
Key Findings
['A 14-year-old girl presented with cough, fever, chest tightness, and chest pain.', 'Chest CT revealed extensive inflammatory consolidation with cavitary change in the right upper lobe.', 'Positive Cryptococcus neoformans capsular antigen in blood and bronchoalveolar lavage fluid confirmed the diagnosis.', 'After treatment with fluconazole, the patient was discharged in stable condition.', 'Follow-up imaging at 16 weeks demonstrated resolution of the lesion.']
Clinical Implications
Clinicians should consider cryptococcosis in pediatric patients presenting with pulmonary cavitation and non-specific respiratory symptoms, especially when there is inadequate response to conventional therapies. Early diagnostic investigations are essential to guide appropriate treatment.
Conclusion
This case underscores the importance of recognizing pulmonary cryptococcosis in immunocompetent children to facilitate timely diagnosis and treatment, potentially reducing morbidity and mortality associated with the disease.
Protection against spread appeared strongest within 6 months of vaccination, while exposed vaccinated contacts showed no measurable reduction in infection risk.
