2. Figure 1
Histopathologic features of usual interstitial pneumonia. A, Low-power view shows marked fibrosis with architectural distortion, honeycombing in a predominantly subpleural distribution with absence of features inconsistent with usual interstitial pneumonia, eg, granulomas, marked inflammation, organizing pneumonia (hematoxylin-eosin, original magnification ×40). B, High-power view shows fibroblast foci, focal pale areas of active fibroblast proliferation at the edge of dense fibrosis (hematoxylin-eosin, original magnification ×100).

3. Figure 2
High-resolution computed tomographic features of usual interstitial pneumonia. A, Axial view shows subpleural predominance of reticular opacities and honeycombing with absence of features inconsistent with a usual interstitial pneumonia pattern, eg, extensive ground-glass opacities, consolidation, micronodules, mosaic pattern (air trapping). B, Sagittal view shows subpleural and basilar predominance of reticular opacities and honeycombing.

4. Figure 3
High-resolution computed tomographic features of acute exacerbation in idiopathic pulmonary fibrosis. Diffuse ground-glass opacities are seen bilaterally, greater on the right, superimposed on underlying usual interstitial pneumonia characterized by reticular opacities and honeycombing in the subpleural tissues.
