Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest radiographs were provided . Multiple dense opacities throughout the lungs correspond to known pleural plaques . However compared to prior studies there appear to be more discrete opacities , particularly in the right lung . This may represent worsening of metastatic disease or infection . The bones are sclerotic compatible with known metastases . Sclerosis in the right humerus is again noted . The cardiomediastinal silhouette is normal . Wedging of multiple thoracic vertebral bodies may have progressed from the prior exam , although visualization is obscured by overlying opacities . There is no pneumothorax or pleural effusion .
    OUTPUT:
    
1 . Pulmonary opacities , corresponding to known calcified pleural plaques . 2 . New opacities particularly in the right lung base may represent metastases versus infection . This can be further clarified by CT as indicated . 3 . Diffuse bony metastases with possible new wedging of multiple thoracic vertebral bodies . , new since ___ .
