Figure 1.
High-resolution CT images show patchy subpleural ground-glass opacities throughout both lungs and alveolar consolidations in both lower lobes. CT, computed tomography.
Figure 2.
Chest X-ray showing an interstitial pattern predominantly involving the mid- and upper-lung zones.
Figure 3.
Transverse, coronal (MPR and MinIP) and sagittal high-resolution CT performed 3 months after the initial episode of dyspnoea showing subpleural and central ground-glass opacities in both lungs, predominantly in the upper lobes, with septal thickening, intralobular lines and distortion without microcysts (pattern suggests NSIP). Consolidations of the lower lobes have disappeared. CT, computed tomography; NSIP, non-specific interstitial pneumonia.
