    INPUT: A large left pleural effusion is unchanged . Adjacent to the pleural effusion there is rounded consolidation , which is presumably atelectasis .

Moderate cardiomegaly is stable . There is no pneumothorax .
    OUTPUT:
    
1 . Large unchanged left pleural effusion . 2 . Decrease in size of right pleural effusion . 3 . No pulmonary edema . 4 . Presumed left basilar atelectasis . If clinically indicated , could better evaluate this consolidation with a CT performed after a thoracentesis .
