3. The chest radiograph shows large lung volumes with faint, thin-walled cystic lesions bilaterally
The chest radiograph shows large lung volumes, which argues strongly against a fibrosing lung process. Patchy perihilar linear and reticular opacities are present, but no infiltrative findings, such as ground-glass opacity and consolidation, are evident. The ascending aorta is mildly tortuous, and is the cause of the right mediastinal contour, but no mediastinal or hilar lymph node enlargement is evident. There are no pulmonary nodules. In addition to the large lung volumes, curvilinear opacities are present, creating the appearance of faintly seen cysts, best appreciated in the left perihilar region. In this area, a small air-fluid level may be present as well (Figure 2).
Figure 2. Frontal chest radiography shows large lung volumes associated with bilateral perihilar linear and curvilinear opacities that create the faint appearance of thin-walled cysts. A small, low air-fluid level (arrows) may be present in the left perihilar region.
