Calcified pleural plaques

Bilateral calcified pleural plaques due to previous asbestos exposure and a right-sided malignant mesothelioma. Chest radiographs shows multiple calcifications en face and in tangent, along the rib cage overlying the lung and along the diaphragm. Complete opacification of the right hemithorax with contralateral mediastinal shift is due to the pleural effusion associated with malignant mesothelioma.
