Incidental Cryptococcal lung mass in an immunocompetent patient
1Department of Internal Medicine, Medstar Harbor Hospital, Baltimore, MD, USA.
Abstract:
Cryptococcus is an encapsulated fungal organism often implicated in central nervous system and pulmonary disease in patients with AIDS or other immunocompromising diseases. However, immunocompetent hosts can also be infected. In these cases, symptoms are generally mild and common radiographic findings include small, well-defined, smoothly marginated pulmonary nodules. We present a case of a 31-year-old man without any immunocompromising factors found to have pulmonary Cryptococcal infection presenting as a large lung mass.
Insights
Pulmonary cryptococcal infections typically cause small nodules in immunocompetent individuals. This case highlights a rare presentation of a large lung mass in an otherwise healthy patient, expanding the differential diagnosis for lung masses.
Area of Science:
- Mycology
- Infectious Diseases
- Pulmonology
Background:
- Cryptococcus is an encapsulated fungus causing disease, particularly in immunocompromised individuals.
- Pulmonary cryptococcosis in immunocompetent hosts usually presents with mild symptoms and small pulmonary nodules.
- Atypical presentations of fungal infections can mimic other pulmonary pathologies.
Purpose of the Study:
- To report a rare case of pulmonary cryptococcal infection presenting as a large lung mass.
- To emphasize the importance of considering fungal infections in the differential diagnosis of lung masses, even in immunocompetent patients.
- To contribute to the understanding of varied clinical and radiographic presentations of Cryptococcus in diverse host populations.
Main Methods:
- Case report of a 31-year-old male patient.
- Review of clinical presentation, radiographic findings, and diagnostic workup.
- Histopathological and microbiological confirmation of pulmonary cryptococcosis.
Main Results:
- The patient was immunocompetent with no underlying predisposing conditions.
- Radiographic imaging revealed a large lung mass, an atypical finding for cryptococcosis in this population.
- Diagnosis was confirmed via microbiological and histopathological examination.
Conclusions:
- Pulmonary cryptococcosis can present as a large lung mass even in immunocompetent hosts.
- This case expands the spectrum of radiographic findings associated with pulmonary cryptococcosis.
- Clinicians should consider Cryptococcus in the differential diagnosis of lung masses regardless of immune status.
