FINDINGS:
Right lung base opacity is increased and left lung base opacity is new since
 .  The opacity at the right lung base is larger than left.  Findings
 are suggestive of superimposed pulmonary edema in the setting of right lung
 base pneumonia.  Lungs are hyperinflated.  Emphysema and biapical scarring are
 similar as before.  Enlarged right hilar silhouette is again noted.  There is
 no pneumothorax.  Bilateral pleural effusions are small.  Cardiac silhouette
 is normal size.

IMPRESSION:
Increasing bibasilar opacities as well as small bilateral pleural effusions
 are likely due to increased superimposed pulmonary edema in setting of right
 pneumonia.
