FINDINGS:
AP single view of the chest has been obtained with patient in
 semi-upright position.  Analysis is performed in direct comparison with the
 next preceding similar study of .  There is no evidence of
 pneumothorax on either side which can be identified with this portable single
 view examination.  Comparison with the next previous study suggests that the
 right-sided massive pleural densities have changed in position slightly and as
 much, there is improved aeration of the right upper lobe area and the
 previously identified large pleural density in the right axillary area
 impressing on the aerated lung tissue has clearly decreased.  On the other
 hand, it is impossible to assess whether the loculated pleural effusion has
 shifted more to the lower areas.  Again, portable chest examination does not
 allow assessment of the right-sided subhilar and parenchymal abnormalities. 
 No new abnormalities are identified in the left hemithorax as there was no
 repeat lateral view, one cannot comment on the amount of pleural effusion on
 the left side identified on the preceding study.  The draining PleurX catheter
 remains in place.
