Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Mild enlargement of cardiac silhouette is re - demonstrated . The mediastinal and hilar contours are similar . Minimal atherosclerotic calcifications are noted at the aortic knob . The pulmonary vasculature is normal . Lungs are hyperinflated but clear without focal consolidation . Minimal blunting of the costophrenic sulci posteriorly may suggest the presence of trace bilateral pleural effusions . Pulmonary vasculature is normal . No pneumothorax is identified . Fracture deformity of the right proximal humerus is re - demonstrated , and appears chronic . Widening of the left AC joint also appears chronic , also reflects prior injury . A BB marker indicating the site of the patient 's tenderness is identified adjacent to the eleventh posterior rib on the right . No acutely displaced fractures are visualized in the vicinity of this marker . There is minimal deformity of the right ninth lateral rib , however this may be chronic .
    OUTPUT:
    
1 . Probable trace bilateral pleural effusions without other acute cardiopulmonary abnormality . 2 . Minimal deformity of the right ninth rib may reflect a chronic fracture . Otherwise , no acutely displaced fracture identified .
