Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with earlier the same day , there is now a small to moderate - sized right upper lobe pneumothorax , new or significantly larger than on the prior film . The right pigtail catheter is again seen , similar in position , allowing for slight rotation . There is relatively minimal atelectasis at the right lung base . There is subcutaneous emphysema over the right chest , which appears more pronounced on the prior study . There is minimal blunting of the right costophrenic angle , which is elevated new or slightly more pronounced . Cardiomediastinal silhouette is probably unchanged and remains midline . Hazy opacity over the left mid and lower zones is seen , but may represent artifact due to overlying soft tissues . There is subsegmental atelectasis at the left lung base . Allowing for this , no CHF , focal consolidation or gross effusion is seen in the left lung .
    OUTPUT:
    
1 . New versus significantly larger small to moderate right upper lobe pneumothorax , with only minimal right lung atelectasis . Right pigtail catheter is minimally rotated , but overall similar in configuration . 2 . New or more pronounced right - sided subcutaneous emphysema . 3 . Minimal blunting of the right costophrenic angle and minimal subsegmental atelectasis left base . 4 . Hazy opacity over left mid and lower zones laterally more likely represents artifact due to overlying soft tissues . However , attention to this area on followup films is requested to exclude a focal opacity .
