Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A new pigtail catheter has been placed into the right pleural space with substantial decrease in a pleural effusion . The cardiac , mediastinal and hilar contours appear stable . There are probably trace pleural effusions bilaterally and persistent opacities at the lung bases , more extensive on the left than right , likely due to atelectasis . There is moderate pleural thickening at each lung apex and a few calcified nodules in the upper lungs , greater on the right than left , most consistent with small calcified granulomas . There are again non-displaced fractures involving the right posterior lateral third and fifth ribs . Subtle fractures of the fourth and sixth ribs are also possible .
    OUTPUT:
    
Decrease in pleural effusion and parenchymal opacification at the right lung base following placement of a chest tube . No pneumothorax . Non-displaced rib fractures on the right .
