Radiopacity projecting at the level of the right hilar structures may represent the aspirated tooth within the right lower lobe superior segment bronchus .
    OUTPUT:
    
1 . Interval improvement in left lung base consolidation . 2 . Moderate left layering pleural effusion with associated atelectasis . 3 . Radiopacity projecting at the level of the right hilum may represent the aspirated tooth .
