Imaging findings
Initial chest CT scan demonstrates a large area of consolidation in the left midlung with surrounding ground-glass opacity and small internal areas of cavitation. Follow-up imaging obtained after antifungal treatment reveals resolution of the surrounding ground-glass opacity and consolidation, leaving a residual, thick-walled cavitary lesion in the left upper lobe.
Key takeaways
Coccidioidomycosis, commonly known as valley fever, is a highly prevalent fungal infection in endemic regions such as Arizona. Although acute pneumonic consolidation and cavitation resolve with therapy, patients frequently retain permanent residual thick-walled cavities or nodules that can remain stable and asymptomatic indefinitely.
