6 Radiographic features of Aspestosis Benign pleural effusion (usually w/in 10 yrs. of exposure) Pleural plaque formation +/- calcification Pleural thickening Rounded atelectasis Pulmonary fibrosis (usually >20 yrs. after exposure) Malignant mesothelioma Bronchial carcinoma

7 Findings/diff diagnosis Nodular shadows associated with short line shadows are seen in fibrosing alveolitis whatever the cause (especially pneumoconioses such as coal workers lungs, tin handlers, aspestosis) Allergic alveolitis Late stage xanthomatous lesions (Histiocytosis X)

8 Aspestosis Amphibole fibers (straight fibers) more carcinogenic than chrysotile (curved fibers) Smokers with aspestos exposure times more likely than nonsmokers to develop bronchogenic carcinoma
