FINDINGS:
The aorta is tortuous with a rounded contour of the right hilum suggesting
 aneurysmal dilatation of the aortic root, not included in the field of view on
 the recent CTA head and neck.  The cardiomediastinal contour is otherwise
 normal.  There is no focal consolidation, pleural effusion, pulmonary edema,
 or pneumothorax.  The osseous structures and upper abdomen are unremarkable.

IMPRESSION:
1. No acute cardiopulmonary process.
 2. Dilated tortuous aorta with concern for aortic root aneurysm.  Further
 evaluation with chest CTA could be considered if clinically indicated.
