The aorta remains tortuous in appearance . There is calcification of the aortic knob . The mediastinal contours are slightly prominent due to unfolding of the aorta but appears stable . The hilar contours are within normal limits . The cardiac silhouette is top normal in size . There is streaky opacification in the right lung apex along the right paratracheal stripe , which may represent atelectasis or aspiration . No significant pleural effusion or pneumothorax is detected .
