There is mild leftward shift of mediastinal structures , similar to prior exams . The visible cardiomediastinal silhouette is unchanged . Increased left central bronchovascular prominence and diffusely prominent interstitial markings throughout the left lung are compatible with pulmonary vascular congestion and mild pulmonary edema . There are no focal lung consolidations . There is no pneumothorax or left pleural effusion .
    OUTPUT:
    
1 . Mild pulmonary edema involving left lung . No evidence of focal pneumonia . 2 . Complete opacification of right hemithorax , consistent with re-accumulation of known large right pleural effusion .
