    INPUT: There is a small amount of subcutaneous air overlying the neck . A lucency adjacent to the aorta may reflect pneumomediastinum . Large left lower lobe consolidation , and opacities in the right lower lobe are presumably from aspiration . No pleural effusion or pneumothorax . Heart is mildly enlarged . The hilar structures are unremarkable . Degenerative changes involve the right glenohumeral joint .
    OUTPUT:
    
1 . Subcutaneous air in the neck and probable , trace pneumomediastinum . Comparison to prior imaging would be helpful . 2 . Left lower lobe consolidation and right lower lobe opacities are likely from aspiration .
