Imaging Findings

(A) Chest radiograph shows mild basilar opacity but is otherwise normal (arrows). (B) Computed tomography (CT) of the chest (lung windows) at the mid-thorax shows symmetric subpleural reticular opacities and micronodules (arrows). (C) CT of the chest (lung windows) at the lung bases shows more extensive reticular opacities, scattered areas of ground-glass opacity, and mild traction bronchiectasis (arrows).
