FINDINGS:
No interval change in the ill-defined right upper lobe opacity. 
 Lungs are otherwise clear with normal pleural surfaces. Lungs are slightly
 hyperexpanded with flattening of the diaphragms, which may be suggestive of
 COPD. Heart size, mediastinal contour and hila are normal. No bony
 abnormality.

IMPRESSION:
