case_images: Chest radiography showed bilateral upper pleural thickening and an elevation of the hilar region of the lungs caused by upper lobe volume loss (Fig. 1A). Chest computed tomography revealed pleural thickening with subpleural fibrosis concentrated in the upper lobes, without lower lobe involvement (Fig. 1E). On chest radiography, at maximum inspiration, there was no difference in the diaphragm position between the standing and supine postures (Fig. 1A and C). However, at maximum expiration, the elevation of the diaphragm was greater in the supine position than in the standing position (Fig. 1B and D), suggesting that the diaphragm moved a greater distance in the supine position than in the standing position.

case_images: DE at tidal breathing was lower in the standing position than in the supine position (13.4 mm vs. 19.2 mm; Fig. 2A and B, respectively). During deep breathing, the distance was lower in the standing position than in the supine position (20.7 mm vs. 44.5 mm; Table 2, Fig. 2C and D, respectively).
