Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged . Small quantities of subcutaneous emphysema are noted in soft tissues overlying the site of insertion of a chest tube into the left hemithorax . It has been pulled back somewhat but appropriately projects over the mid hemithorax , making a turn beyond the side holemarker . No detectable pneumothorax remains in the left hemithorax . Minimal opacification of the left lower lung is probably due to minor atelectasis . The right lung remains clear . There is no definite pleural effusion . Left - sided rib fractures are not well characterized .
    OUTPUT:
    
Chest tube projecting over the left hemithorax . Small quantity of subcutaneous emphysema but no residual pneumothorax identified .
