Figure 1 Chest high-resolution computed tomography (HRCT) images. A-C: showing traction bronchiectasis and extensive fibrosis, reticular changes (especially in the outer lung band and the double lower lung); D-F: showing the corresponding mediastinal window.

Figure 2 Pathological findings of transbronchial lung biopsy (TBLB) and computed tomography (CT)-guided percutaneous lung puncture, hematoxylin and eosin staining (×400). A: chronic lymphocyte infiltration; B: foamy macrophages infiltration and diffuse, relatively uniform alveolar septal thickness; C: hyperplasia of fibrous tissue in the bronchial wall, resulting in fibrosis.
