FINDINGS:
An extensive right hilar lung mass is associated with radiation
 fibrosis, better delineated on CT .  An additional component of
 postobstructive pneumonia may be present.  Retrocardiac opacity, left pleural
 effusion, and left plueral thickening are also new.  No pneumothorax is
 present.

IMPRESSION:
1.  Large right hilar lung mass and radiation fibrosis.  Additional
 post-obstructive pneumonia in the right upper and lower lobes is possible but
 hard to delineate.
 2.  New left retrocardiac opacity, small left effusion, and pleural
 thickening.
 
 Findings were discussed with , RN, via telephone at  and
