    INPUT: There has been interval , likely increase in large right - sided pleural effusion , given differences in technique . Underlying consolidation is not excluded . There are patchy opacities projecting over the left mid - to - lower lung which could be due to multifocal infection versus less likely edema . The mediastinal and cardiac silhouettes are not well assessed due to the large right - sided opacity from pleural effusion , however , the right aspect of the mediastinum and heart appear unremarkable . No large left pleural effusion is seen . There is no evidence of pneumothorax .
    OUTPUT:
    
1 . Interval increase in large right pleural effusion , underlying consolidation can not be excluded . 2 . Patchy opacities in the left mid - to - lower lung raise concern for multifocal infection , aspiration , edema felt less likely .
