Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is borderline in size . The aorta is mildly tortuous with calcification along the arch . There is no pleural effusion or pneumothorax . In addition to a very mild diffuse interstitial process , probably vascular congestion , there is a focal opacity that includes some tethering to the right apical pleural surface with streaky opacities and volume loss , somewhat suggestive of chronic scarring . Right suprahilar opacity appears irregular but not very dense , possibly an additional area of scarring , less likely pneumonia ; however primary neoplasm is also a differential diagnosis .
    OUTPUT:
    
1 . Mild interstitial abnormality as the suggestive of vascular congestion . Differential considerations may also include atypical pneumonia in the appropriate setting . 2 . Focal right suprahilar and right apical peripheral opacities . These may be due to chronic scarring but other etiologies including acute infection or even primary neoplasm are not excluded by this study . Comparison with any prior studies is recommended , if available ; otherwise short - term follow - up evaluation with chest CT is recommended to reassess .
