Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is moderately enlarged . There is a convex contour to the right upper mediastinum that is most often due to tortuosity of the great vessels , although not entirely specific . Mild diffuse interstitial abnormality including prominence of upper zone pulmonary vascularity , which also appears indistinct , suggests mild pulmonary vascular congestion . Patchy and medial left lower lung opacities suggest minor atelectasis . Surgical clips project along the left axilla . Moderate degenerative changes involve the right glenohumeral joint , which shows moderately large osteophytes .
    OUTPUT:
    
1 . Findings suggesting mild pulmonary vascular congestion . 2 . Convex contour to the right upper mediastinum , which usually coincides with tortuosity of vasculature , but is not specific and could represent lymphadenopathy , for example . Correlation with prior radiographs is recommended to see whether this appearance can be shown to have long - term stability . Otherwise , short - term followup radiographs or evaluation with CT is recommended to evaluate further .
