    INPUT: Pigtail pleural catheter remains in place in the left hemithorax . A very large left pneumothorax is present , and has increased in size since the prior study . The apical visceral pleural line is at the level of the inferior aspect of the left fifth posterior rib . Due to slight rightward patient rotation , it is difficult to assess for signs of tension , but note is made of slight widening of the rib interspaces on the left , which could indicate the presence of tension . Small loculated hydropneumothorax components are also visualized , best seen on the lateral radiograph . Left basilar atelectasis is present . Right lung and pleural surfaces are clear .
    OUTPUT:
    
Increasing , large left pneumothorax with possible tension . This finding has been communicated by telephone with Dr . ___ at 9 : 25 a .m . on ___ at the time of discovery .
