    INPUT: A newly placed pigtail drainage catheter projects over the right lung base . Despite this , large bilateral pleural effusions with adjacent atelectasis have increased from prior . There is no pneumothorax . Assessment of the cardiac silhouette is limited . The mediastinal contours are unchanged . A rounded opacity at the right lung base is likely atelectasis .
    OUTPUT:
    
1 . No pneumothorax after drainage catheter placement . Increasing large bilateral pleural effusions . 2 . Rounded opacity at the right lung base is likely atelectasis . Attention to this area on follow - up after drainage is recommended .
