Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The patient is rotated to the right with respect to the film . Rotated position exaggerates mediastinal widening and a convexity along the aortic contour , which corresponds to the patient 's known descending thoracic aortic aneurysm . Cardiomediastinal contours are otherwise unchanged . Bibasilar atelectasis is again seen . There is no focal pulmonary consolidation , pneumothorax , or pleural effusion . There is exaggerated kyphosis of the thoracic spine . The osseous structures are otherwise unremarkable , and there is no evidence of rib fracture . No radiopaque foreign bodies .
    OUTPUT:
    
1 . No rib fracture seen . 2 . Rotated position exaggerates convexity of the known descending thoracic aortic aneurysm , preventing assessment for subtle interval change .
