Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Following placement of a right pigtail pleural catheter , large partially loculated right pleural effusion has decreased in size , particularly in the lower right hemithorax near the catheter . In this same region , focal hyperlucency likely represents a loculated pneumothorax . Extensive right upper lobe consolidation has worsened in the interval . Right mid and lower lung atelectasis adjacent to the loculated effusion have improved with residual opacity which could reflect combination of resolving atelectasis and reexpansion edema , although additional site of infection is possible in the setting of right upper lobe pneumonia . Large left loculated pleural effusion and adjacent left mid and lower lung atelectasis are unchanged .
    OUTPUT:
    
1 . Decreased size of right pleural effusion following pigtail pleural catheter placement , with development of a small loculated pneumothorax . 2 . Worsening right upper lobe pneumonia .
