Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: As compared to prior chest radiograph , there is increased density of the right lower lobe which is likely related to a moderate amount of pleural fluid with a subpulmonic component , in combination with known abdominal ascites . There is a small left pleural effusion . There is a dense paratracheal opacity which likely relates to partial right upper lobe collapse . There are worsening opacities at the lung bases bilaterally which could represent atelectasis , aspiration or pnuemonia . There is no pneumothorax .
    OUTPUT:
    
1 . Moderate right pleural effusion and small left pleural effusion . 2 . Worsening opacities at lung bases bilaterally which may represent atelectasis , aspiration , or developing pneumonia . 3 . New right uper lobe paratracheal opacity , likely due to partial right upper lobe atelectasis .
