Fig. 4From: Pleuroparenchymal fibroelastosis: role of high-resolution computed tomography (HRCT) and CT-guided transthoracic core lung biopsyAxial high-resolution chest tomography (HRCT) images (a–d) of patient 4 show pleural and subpleural thickening with moderate fibrotic changes in the marginal parenchyma with apical-caudal distribution. These features are more evident in the right lobe. Note also, in c, a slight “tree-in-bud” pattern in the middle lobe compatible with concomitant pulmonary infectionBack to article page
