    INPUT: A left - sided pigtail catheter is unchanged in position compared to the prior study . A right - sided internal jugular Port - A - Cath terminates in the distal SVC or right atrium . There is a small amount of subcutaneous air in the left chest wall . No pneumothorax seen . The the previously demonstrated left apical pneumothorax is not clearly seen . Small right pleural effusion . Increased opacity at the right lung base likely reflects a atelectasis .
    OUTPUT:
    
Left apical pneumothorax is less well seen than on the prior study . Otherwise , no significant interval change . Unchanged right pleural effusion with likely compressive atelectasis .
