Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is mildly enlarged . The aorta is tortuous . The aortic arch is heavily calcified . There is a convex contour to the right upper mediastinum , fairly typical for mediastinal contour frequently seen with tortuosity of the great vessels , but are not specific . Other etiologies including lymphadenopathy or a large thyroid nodule could be considered . A band - like opacity in the lingula suggests minor atelectasis or scarring . There is also streaky posterior left basilar opacity which suggests minor atelectasis or scarring . There is more generally a mild interstitial abnormality suggesting slight vascular congestion , including peribronchial cuffing , although possibly airway inflammation could yield a similar appearance . There is no pleural effusion or pneumothorax . The bones appear demineralized . Mild degenerative changes are noted along the mid thoracic spine , which also demonstrates mild rightward convex curvature centered along the lower thoracic spine .
    OUTPUT:
    
1 . Mild interstitial abnormality which could be seen with mild vascular congestion , although other etiologies such as airway inflammation could be considered . 2 . Abnormal right upper mediastinal contour ; although this appearance is frequently seen with benign tortuosity of the great vessels , investigation with chest CT is recommended when clinically appropriate , unless more remote prior radiographs are available to show long - term stability of this appearance . This finding and recommendation for chest CT was documented in the clinical ER discharge summary .
