Chest radiograph and CT were obtained on the day of admission.
Initial chest radiograph (Figure 1) shows ground glass opacities and reticular opacities with peripheral and lower lung predominance. Axial thin-section CT images (Figure 2-4) and coronal reformatted images (Figure 5 and 6) on the same day as (Figure 1) show patchy areas of ground glass opacity with crazy paving appearance and mixed pattern of ground glass opacity and consolidation in both lungs, with subpleural and peribronchial distribution. Also note reticulation, ground glass opacity, traction bronchiectasis and honeycoming in the subpleural areas of both lungs, suggesting usual interstitial pneumonia.
