4. Figure 3
(A) A transbronchial biopsy revealed focal air space consolidation composed of intra-alveolar fibroblastic foci or Masson's bodies (arrows) (hematoxylin and eosin, 10×). (B) Background lung tissue showed alveolar septal thickening with a mixed inflammatory infiltrate that included neutrophils, plasma cells, lymphocytes, and eosinophils. Reactive type II pneumocytes lined the alveoli.

5. Figure 4
Follow-up computed tomography was conducted 4 weeks after initiation of corticosteroids. (A, B) The mass-like infiltrate resolved, but there was residual scarring in the left upper lobe. (C) Nodules were evident along the fissure, pleura, and base of the left lung. (D) Nonetheless, the nodules were significantly reduced in size.
