Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval placement of a right - sided catheter with pigtail projecting over the liver . A persistent moderate size right pneumothorax remains with continued leftward shift of mediastinal structures as seen on the chest CT scout . Increased subcutaneous emphysema in the right lateral chest wall is noted . Streaky opacities are noted in the right lung likely reflective of atelectasis . Low lung volumes are present which results in crowding of bronchovascular structures and left basilar atelectasis . Cardiac and mediastinal contours otherwise remain unchanged . Right lateral rib fractures are better assessed on the previous CT .
    OUTPUT:
    
Interval placement of right - sided catheter with pigtail projecting over the liver . Persistent moderate size right pneumothorax with continued mild leftward shift of mediastinal structures . Patchy atelectasis in both lungs . Increased subcutaneous emphysema in the right lateral chest wall .
