Pulmonary fibrosis and emphysema: Is the emphysema type associated with the pattern of fibrosis?

Figure 1 Paraseptal emphysema and usual interstitial pneumonia-pattern of pulmonary fibrosis. A: High resolution computed tomography (HRCT) at the level of the upper lobes shows paraseptal emphysema associated with subpleural reticular pattern and minimal ground glass opacity; B: HRCT of the same patient as in A, at the level of the lower lobes reveals extensive coarse reticular pattern characterized by traction bronchiectasis associated with ground glass opacity and subpleural honeycombing. The HRCT pattern is consistent more with usual interstitial pneumonia.
