IMPRESSION:
As compared to  radiograph from 2 hr earlier, a large right
 pneumothorax has substantially decreased in size, with residual moderate
 pneumothorax remaining, with right pigtail pleural catheter in place. Along
 with partial re-expansion of the right lung, atelectasis in the right mid and
 lower lung have partially improved.  Within the left lung, a small left apical
 pneumothorax is again demonstrated, along with improving left basilar
 atelectasis. No other relevant changes since recent study.
