FINDINGS:
The heart is mildly enlarged.  The aorta is tortuous and calcified
 to a mild degree.  There is no pleural effusion or pneumothorax.  There is a
 mildly prominent central vascular and interstitial opacification, suggesting
 mild pulmonary vascular congestion.  In addition, projecting over the right
 lateral lung there is a nodular round density measuring 8 mm in diameter, but
 suspected to represent a nipple shadow.  Moderate degenerative osteophyte
 formation is noted along the anterior thoracic spine, probably unchanged.

IMPRESSION:
Findings suggesting mild pulmonary vascular congestion.  Nodular
 density projecting over the right mid lung, most likely a nipple shadow, but a
 pulmonary nodule cannot be excluded.  When clinically appropriate, a repeat PA
 view with nipple markers is suggested for confirmation.
