FINDINGS:
New interstitial opacities in the left mid lung and lower lobe are suspicious
 for pneumonia.  A nodular opacity in the left retrocardiac region was more
 fully characterized on the recent CT of .  Pleural thickening
 and calcified pleural plaques are again noted.  Basilar predominant
 interstitial lung disease has progressed since  and has been more fully
 characterized on recent chest CT of  The interstitial lung
 disease have progressed since .  Lungs are hyperinflated.  There is no
 pleural effusion.  Cardiomediastinal silhouette is normal size.

 suspicious for pneumonia.  Followup radiograph is recommended  weeks after
 the completion of treatment to ensure and resolution.
 2. Pleural thickening and calcified pleural plaques  suggest history of
 asbestos exposure.
 3. Chronic interstitial lung disease is suggestive of asbestosis in the
 setting of calcified pleural plaques.
 
 RECOMMENDATION(S):  Followup radiograph is recommended 4 weeks after the
