FINDINGS:
Frontal and lateral views of the chest.  There is mild pulmonary
 edema superimposed on the known chronic lung disease.  A small focal area of
 opacification is seen at the right lung base.  There are small bilateral
 pleural effusions, best appreciated on the lateral view.  No pneumothorax. 
 Cardiac size is moderately enlarged.  Coronary stent is also noted.  A
 calcified and tortuous aorta is present.

IMPRESSION:
1.  Mild pulmonary edema superimposed on known chronic lung disease.
 2.  Increased opacification right lung base, worrisome for pneumonia in the
 correct clinical setting.
