Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is no focal consolidation or pneumothorax . A ~ 1 cm nodular opacity is identified just superior to the right hilus . There is no vascular congestion or pleural effusions . A convex contour arising from the descending and ascending thoracic aorta appears unchanged compared to prior and corresponds with known aneurysmal dilatation of the ascending and descending thoracic aorta . Known aortic valvular calcifications are not well seen on this radiographic examination , though may reflect underlying aortic stenosis . The remainder of the mediastinal and hilar contours are within normal limits .
    OUTPUT:
    
1 . ~ 1 cm nodular opacity in the medial right upper lobe . Findings may reflect parenchymal nodule or overlapping vasculature . Repeat PA and lateral should be completed for further assessment if CT is not done 2 . Aneurysmal dilation of the ascending and descending thoracic aorta . Dedicated chest CT should be completed to assess stability since prior CT was from ___ year prior .
