Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Redemonstrated is extensive subcutaneous emphysema . This reduces the sensitivity for detecting pneumothorax ease . The right - sided chest tube appears to be in slightly changed position , as it may have been pulled back . It may still remain in the chest posteriorly , though definite location is difficult to determinate . Right pneumothorax is likely unchanged . Possible left , small apical pneumothorax may be present . Again seen are bibasilar opacities , not significantly changed since the prior .
    OUTPUT:
    
Overall stable examination since the prior with possible displacement of the right - sided chest tube . Bilateral pneumothoraces do not appear to have increased in size .
