4. Chest radiography shows an interstitial abnormality consisting of reticular and nodular opacities
The frontal and lateral chest radiograph show fairly symmetric, bilateral linear, reticular, and faintly nodular opacities without a clear zonal distribution. While some nodular elements are evident, the pattern is not that of miliary disease. Some linear opacities with some faint architectural distortion may be evident, the appearance is not the basilar, peripheral or frankly subpleural reticulation associated with low lung volumes that directly suggests basal fibrotic lung disease; note that the lung volumes in Figure 1 appear relatively normal. No mediastinal mass is evident. The heart size is upper normal, but the cardiomediastinal contour is otherwise unremarkable. No evidence of cavitary lung disease is present.
