CTICasesPulmonary Blastomycosis
Imaging findings
Chest CT shows a single, thin-walled cavitary lesion containing a small dependent fluid level or mobile density simulating a fungus ball in the left lung apex.
Key takeaways
Pulmonary blastomycosis can occasionally present as a thin-walled chronic cavity, mimicking coccidioidomycosis or tuberculosis, rather than its more typical presentation as a mass-like consolidated lesion. Cavities resulting from fungal infections tend to thin out over time as the acute inflammatory component subsides.
