FINDINGS:
PA and lateral chest radiographs demonstrate a stable cardiomediastinal
 silhouette.  Ectatic ascending aorta is better appreciated on dedicated chest
 CT dated .  Lungs are clear without a focal opacity convincing
 for pneumonia.  There is no pneumothorax, pulmonary edema, or pleural
 effusion.  Right apical scarring is noted and correlates with chest CT,
 unchanged allowing for differences in modality.  Multilevel degenerative
 changes are present within the imaged thoracic spine.

IMPRESSION:
No acute intrathoracic abnormality.  Ectatic ascending aorta better
 appreciated on dedicated chest CT dated .
