FINDINGS:
Since the radiograph from 3 hr prior, there is no relevant change. No
 pulmonary edema or pneumonia. No pneumothorax.  Left pleural effusion is
 slightly smaller. Right pleural effusion is unchanged.  Moderate cardiomegaly
 is stable.
 
 This examination neither suggests nor excludes the possibility of pulmonary
 embolus.

IMPRESSION:
Minimally smaller left pleural effusion, otherwise no change.
