Imaging and pathological findings of Patient 1. A) Chest radiograph showing patchy consolidations in both lungs. B) Chest computed tomography showing patchy, peribronchial consolidations with air bronchograms and ground-glass opacities in both lungs. C) Microphotographs of a specimen obtained via transbronchial lung biopsy showing lymphocytic alveolitis and plugs of granulation tissue within airspaces (Hematoxylin and Eosin staining; original magnification, ×100). D) Chest radiograph obtained after 10 months of follow-up showing almost complete resolution of the consolidations in both lungs.
