Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with earlier the same day , the left apical pneumothorax is still small , but considerably larger . The pneumothorax component at the left base also appears slightly larger . Minimal lucency adjacent to the lateral aspect of the aortic knob may also represent part of the left lung pneumothorax , though continued attention to this area to assess for any mediastinal air is requested . Again seen is extensive subcutaneous emphysema along the left chest wall , left pectoralis , and left supraclavicular region . The left chest tube appears similar in appearance , though the sideport now overlies the cardiac silhouette ( previously overlying the mid lung , just above the edge of the heart ) . The right - sided pneumothorax is also slightly larger , now seen tracking from the right apex along the right wall to the right costophrenic angle and adjoining right lung base . There is minimal atelectasis , but no significant collapse , on the right . The mediastinum remains grossly midline . The cardiomediastinal silhouette is similar to the prior study . Retrocardiac opacity is similar to the prior film . Doubt CHF .
    OUTPUT:
    
1 . Left apical pneumothorax still small , but considerably larger . Left base pneumothorax also slightly larger . 2 . Minimal lucency adjacent to the the aortic knob may also represent part of the left lung pneumothorax . Attention to this area on followup films to exclude any mediastinal air is requested . 3 . Extensive subcutaneous emphysema , equivocally slightly greater than on the prior film . 4 . Minimal interval change in position of the left chest tube . 5 . Right pneumothorax also increased , still small in width , but now seen not only at the right lung apex , but also along the right lateral chest wall and at the right costophrenic angle in the adjoining lung base .
