FINDINGS:
Portable AP upright chest radiograph shows improved aeration at the
 right lung base, presumably status post right-sided thoracentesis.  No
 pneumothorax is visible.  The left hemidiaphragm remains obscured and there
 appears to be increased haziness of the mid and upper lung zone compared to
 the study from eight hours earlier.  Some of this may be exaggerated because
 of increased rotation.  Left-sided PICC line tubing may be slightly pulled
 back and now is at the level of the mid superior vena cava.
