Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Two frontal images of the chest demonstrate interval redevelopment of a right - sided pleural effusion . The effusion forms an air - fluid level , suggesting persistent pneumothorax , even though pneumothroax was less conspicuous on previous exam than on the post - procedure exam . There is interval worsening of the right lung base opacity , consistent with the reaccumulating right pleural effusion . The large left pleural effusion remains unchanged from prior imaging . The right - sided PICC line and pacer wires are again noted in the expected course , unchanged from previous imaging . Cardiomediastinal silhouette can again not be characterized given obscuration by bilateral pleural effusions .
    OUTPUT:
    
Persistent pneumothorax with newly reaccumulating right pleural effusion with associated air-fluid level ( hydropneumothorax ) . Large left pleural effusion unchanged .
