    INPUT: Single frontal view of the chest . Two pleural drains are in stable position , terminating in the right lung apex . There is now near - complete opacification of the right hemithorax with some mild associated shift of mediastinal structures to the right , suggestive of right lung collapse . These changes appear superimpose all preexisting re-expansion edema and residual consolidation . Small left pleural effusion persists and there is likely a right effusion as well . Widespread pulmonary metastases are redemonstrated .
    OUTPUT:
    
Near - complete opacification of the right hemithorax with mild rightward shift of mediastinal structures , suggestive of right lung atelectasis , which is likely superimposed on pre-existing re-expansion edema . Coexisting effusion is likely .
