Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: As before , there are four sternotomy wires , scattered right hemithoracic surgical clips , and skin ___ along the lateral aspect of the right chest wall . There has been a marked increase in what is now near - complete homogeneous opacification of the right hemithorax with a slight rightward shift of the mediastinal structures , consistent with atelectasis in the setting of interval mucus plugging . A portion of the known moderate right hydropneumothorax is visualized at the right lung apex . Interstitial opacities throughout the left lung , more prominent in its mid - to - upper portion , are not significantly changed , consistent with mild - to - moderate interstitial pulmonary edema . There is no left pleural effusion . The heart size is difficult to assess but is likely unchanged . Again noted are right - sided rib defects as well as resection of the distal portion of the right clavicle .
    OUTPUT:
    
1 . New near - complete opacification of the right hemithorax , consistent with atelectasis in the setting of mucus plugging . 2 . Partial visualization of known right hydropneumothorax , likely unchanged in size . 3 . Left lung interstitial opacities consistent with mild - to - moderate pulmonary edema , not significantly changed . Findings were discussed with Dr . ___ by Dr . ___ at 9 :05 a .m . via telephone on the day of the study .
