Coccidioidomycosis-Induced Organizing Pneumonia
Imaging findings
CT chest shows multiple, patchy consolidations with surrounding ground-glass halos in an organizing pneumonia pattern, with peripheral eosinophilia. Biopsy and serology confirmed Coccidioides immitis infection.
Key takeaways
Coccidioidomycosis can trigger a secondary immunological reaction, manifesting as organizing pneumonia or eosinophilic pneumonia. In patients from endemic areas, checking for fungal serology is important prior to initiating corticosteroid therapy to avoid fungal dissemination.
