7 Radiography May be normal (10-20%) Peripheral lower zone predominance Irregular reticular or small nodular opacities"Shaggy" cardiac silhouette in advanced diseaseLate: Endstage honeycombingPleural plaques (25%)Lung cancer: Lower zone predominance in contrastto the upper zone predominance in the general population of smokersProgressive massive fibrosis extremely rare
8 Small subpleural nodules (straight arrows), Patchy ground-glass opacities (curved arrows),Interlobular septal thickening (arrowhead) suggestive of early-stage asbestosis.
9 Pleural plaque : band like pleural thickening (arrowheads) in the lower lobe of both lungs
10 Asbestosis : subpleural consolidation (arrow) in the lower lobe of the left lung, with reticulation, ground-glass opacities, and honeycombing
11 Pt with asbestos exposure: subpleural consolidation (arrow), pleural thickening (arrowheads) and effusion.
13 Subpleural Linescurvilinear opacity a few millimeters or less in thickness,less than 1 cm from the pleural surfacenonspecific indicator of atelectasis, fibrosis, or inflammationmore common in patients who have asbestosis than in those who have IPF or other causes of UIP
15 Asbestosis VS idiopathic pulmonary fibrosis IPF more basal and sub pleural fibrosispresence of parietal pleural thickening in association with lung fibrosis is the most important feature differentiating asbestos-induced pulmonary fibrosis from IPFasbestos bodies in bronchoalveolar lavage fluid
