Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are reduced . The heart size is mildly enlarged with dense mitral annular calcifications noted . Aortic knob is calcified . There is crowding of the bronchovascular structures , but no pulmonary edema is demonstrated . The hilar contours are unremarkable . Peripheral patchy opacities are noted projecting over the right upper and mid lung fields which are unchanged and may be attributable to a chronic interstitial abnormality . Patchy opacities within the left mid and lower lung fields may reflect areas of atelectasis or infection . Minimal blunting of the right costophrenic angle is chronic and compatible with pleural thickening . No pleural effusion is otherwise seen . No pneumothorax is identified . Remote left - sided rib fractures are seen .
    OUTPUT:
    
Patchy opacities within the left mid and lower lung fields may reflect atelectasis or infection . Chronic opacities within the right upper and mid lung fields peripherally .
