    INPUT: AP upright and lateral chest radiographs demonstrate well expanded lungs . Cardiomegaly is unchanged . The cardiomediastinal contours are otherwise unremarkable .

Right humeral head fracture with increased subacromial space is better assessed on dedicated radiograph of the right shoulder from the outside hospital .
    OUTPUT:
    
1 . Emphysema / ILD without superimposed pneumonia . 2 . Known right humeral head fracture .
