FINDINGS:
Comparison is made to prior study from .
 
 There is a right-sided PICC line with distal lead tip at the cavoatrial
 junction.  There are low lung volumes with atelectasis at the lung bases and a
 left retrocardiac opacity.  This is unchanged.  Surgical clips within the left
 axilla are again seen.  There are several healed old right-sided rib
 fractures.  No pneumothoraces are seen.
