FINDINGS:
Overall appearance of the chest is relatively similar to the recent
 study except for worsening left retrocardiac opacity which probably represents
 a combination of small-to-moderate left pleural effusion and adjacent left
 lower lobe atelectasis and/or consolidation; additionally, patchy and linear
 opacities at the right lung base have also slightly worsened.  Remainder of
 lungs are clear, and cardiomediastinal contours are stable.
