Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is mildly enlarged with a left ventricular configuration . There is mild tortuosity of the thoracic aorta . The upper mediastinal border shows a smooth convex contour , most often seen with tortuosity of great vessels , although not entirely specific . Patchy retrocardiac opacity is noted with elevation of the left hemidiaphragm , mild in degree , suggesting volume loss . There is also a patchy focal opacity projecting over the right lower lung with peribronchial cuffing . It is difficult to exclude a pleural effusion on the left . There is no pneumothorax .
    OUTPUT:
    
1 . Patchy basilar opacities , including volume loss at the left base and retrocardiac opacification . This appearance could be seen with atelectasis or airway inflammation , but pneumonia could be considered in the appropriate clinical setting . Short - term follow - up radiographs may be helpful to evaluate further , if clinically indicated , preferably with standard PA and lateral technique if possible clinically . 2 . Convex contour to the right upper mediastinum , which is likely to reflect tortuosity of the great vessels . However , given the setting of known malignancy it is difficult to exclude other etiology such as lymphadenopathy . Accordingly , if available , direct comparison to earlier radiographs is suggested to assess for stability of this appearance . Discussed with Dr . ___ at 12 :30 pm on ___ by telephone .
