Diffuse Pleural Thickening in a 63-year old man with a history of asbestos exposure – Lateral chest radiography (a) shows a smooth uninterrupted pleural opacity extending over at least a fourth of the anterior chest wall. Note some small linear opacities in the adjacent lung parenchym(arrows). Axial CT image in soft tissue window (b) demonstrates a partially calcified pleural thickening associated with a hypertrophy of the subpleural fat (arrows). Sagittal CT image in lung window (c) shows parenchymal bands adjacent to the pleural thickening as a result from the fusion of the two pleural layers.
