Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There has been significant interval development of a large right - sided pleural effusion layering along the right lateral pleural surface . There also appears to be increased opacification of the right lung which may be secondary to layering fluid . In the context of the increased opacification of the right lung , a new focal consolidation can not be excluded . The left lung also demonstrates increased peripheral opacities which may be secondary to atelectasis given their development in the last three days , however an infectious etiology can not be ruled out . The left lung volume is low . The heart size is unchanged . There is no pneumothorax .
    OUTPUT:
    
1 . Significant interval development of a large layering right - sided pleural effusion . In the context of the background opacification of the right lung , any focal consolidation of infectious etiology or otherwise can not be ruled out . 2 . Interval development of peripheral left mid-lung focal opacities . This may be secondary to atelectasis ; however , again a left - sided focal infectious consolidation can not be ruled out . These findings were discussed with Dr . ___ at 10 : 30 am by Dr . ___ ___ by telephone on the day of the exam .
