FINDINGS:
The lungs are clear of consolidation. Increased interstitial markings are seen
 although these appear chronic. There is moderate cardiomegaly which is
 unchanged. Atherosclerotic calcifications are noted at the aortic arch.
 Leftward deviation of the trachea at the thoracic inlet is due to known
 right-sided thyroid enlargement. Old left posterior ninth rib fracture again
 identified.

IMPRESSION:
No acute cardiopulmonary process.
