Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The apical pleural drain remains in place , slightly different in configuration . A very tiny left apical pneumothorax is likely present . No gross left - sided effusion . Minimal subcutaneous emphysema and 2 surgical clips again noted along the lower left chest . Inspiratory volumes are slightly lower , with atelectasis now seen at right - greater - than - left bases . Allowing for this , the cardiomediastinal silhouette is probably unchanged . No CHF . No focal consolidation or gross effusion . Again seen is the left subclavian indwelling catheter , with tip at distal most SVC .
    OUTPUT:
    
Likely tiny left apical pneumothorax . Slight change in configuration of the left apical pleural drain noted . Inspiratory volumes slightly lower , with new subsegmental atelectasis the right - greater - than - left bases . Otherwise , doubt significant interval change .
