Fig. 13. A 75-year-old male with history of woodworking and mold exposure demonstrating non-fibrotic hypersensitivity pneumonitis. Non-contrast axial (A, B) and coronal (C) chest computed tomography images show diffuse centrilobular ground-glass nodularity with inspiratory mosaicism. Non-contrast expiratory axial (D), coronal (E), and minimum intensity projection (F) images show air trapping.
