    INPUT: The left lung base is densely opacified by a combination of pleural effusion and lower lobe collapse . Heterogeneous density in the right lower hemithorax is also likely a combination of pleural effusion and atelectasis . A large area of vaguely increased radiodensity in the right upper lobe is probably consolidation . Heart size is top - normal . There is no pneumothorax .
    OUTPUT:
    
1 . Left pleural effusion and lower lobe collapse . Smaller right pleural effusion and less severe atelectasis . 2 . Right upper pneumonia .
