Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A left - sided pacemaker and leads are in appropriate position . Heart size is mildly enlarged . The mediastinal and hilar contours are unremarkable . The pulmonary vasculature is normal . Lungs are hyperinflated without focal consolidation . Streaky opacities at both lung bases likely reflect atelectasis . The bronchial tree is calcified and there is mild dilatation of the bronchi particularly in the lung bases suggestive of bronchiectasis . No pleural effusion or pneumothorax is seen . Deformity of the right - sided ribs likely reflect remote rib fractures . No acutely displaced fractures seen .
    OUTPUT:
    
Mild bibasilar atelectasis . No acutely displaced fractures identified .
