Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal and enteric tubes remain in unchanged positions . There has been interval placement of a left basilar chest tube . There is continued near complete opacification of the left hemi thorax with probable leftward shift of mediastinal structures suggestive of atelectasis / collapse . Patchy opacity in the right lung base also likely reflects an area of atelectasis . No overt pulmonary edema or large pneumothorax is present . Known fractures of the right anterior ribs are not well assessed on the current radiograph
    OUTPUT:
    
Interval placement of left basilar chest tube . Otherwise no substantial interval change in the near complete opacification of left hemithorax likely related to atelectasis / collapse .
