Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is increased opacification over the right lung , likely due to increase in loculated pleural effusion , underlying atelectasis , with concern for worsening of metastatic disease , underlying consolidation or infection not excluded . Increased opacification of the right upper lobe may represent increased tumor spread although infection is not excluded . The patient is rotated to the right , however , library deviation of the trachea suggest partial lung collapse , likely obstruction from tumor . Increasing nodular opacities diffusely throughout the lower left lung is highly concerning for progression of metastatic disease . A small left pleural effusion is difficult to exclude . Diffuse osseous metastases better evaluated on CT .
    OUTPUT:
    
Significant interval increase and opacification of the right lung , probably due to increase in underlying loculated right pleural effusion , but also concerning for progression of metastatic disease . Underlying consolidation due to infection is difficult to exclude .
