Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been interval placement of a right - sided chest tube with tip projecting over the mid right lung field , and side port appears to be at the level of the lateral thoracic ribcage with a small amount of subcutaneous emphysema . Previously noted right hydropneumothorx with large right pleural effusion component has slightly decreased in size compared to the prior study , with a small amount appearing to be loculated in the major fissure . The small right apical pneumothorax component appears unchanged . There is continued right basilar opacification compatible with compressive atelectasis . Previously noted leftward shift of mediastinal structures has resolved . Left lung remains hyperinflated with atelectasis in the left lung base . Heart size is mildly enlarged . Left - sided pacemaker device is seen with lead terminating in the right atrium . Mild right - sided pulmonary vascular congestion is present . Extensive degenerative changes of both glenohumeral joints are noted .
    OUTPUT:
    
1 . Interval placement of right sided chest tube with side port at the level of the lateral rib cage . Interval decrease in size of large right hydropneumothorax with the small right apical pneumothorax component appearing relatively unchanged . 2 . Previously noted leftward shift of mediastinal structures has improved . 3 . Persistent right basilar opacity , likely compressive atelectasis . 4 . Mild asymmetric right pulmonary vascular congestion .
