    INPUT: Portable semi-upright radiograph of the chest demonstrates low lung volumes with resultant bronchovascular crowding . Diffuse bilateral infiltrates are stable over the interval , and likely represent a combination of atelectasis and pulmonary edema . There has been interval removal of the right - sided chest tube . Dense retrocardiac opacification likely represents atelectasis . Small left - sided pleural effusion . The cardiomediastinal and hilar contours are unchanged . No pneumothorax . Subcutaneous gas in the bilateral supraclavicular soft tissues is slightly increased as compared to the prior . I
    OUTPUT:
    
1 . No pneumothorax . Slight interval increase in subcutaneous gas in the bilateral supraclavicular soft tissues is concerning for air leak . 2 . Diffuse bilateral infiltrates are stable over the interval , and likely represent a combination of atelectasis and pulmonary edema . New dense retrocardiac opacification likely represents atelectasis .
