Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size is normal . Lung volumes are low . Biapical fibrotic changes with traction bronchiectasis is re - demonstrated . Minimal blunting of the left costophrenic angle suggests a trace left pleural effusion . Streaky bibasilar airspace opacities likely reflect atelectasis . No pneumothorax is identified . Known fracture of the left 11th rib is not clearly delineated on this exam . Clips are seen projecting over the left upper quadrant . No new fractures are seen . There is crowding of the bronchovascular structures but no overt pulmonary edema is demonstrated .
    OUTPUT:
    
Chronic fibrotic changes within both lung apices . Low lung volumes with probable bibasilar atelectasis , though infection or aspiration can not be excluded . Small left pleural effusion . Known left 11th rib fracture is not clearly seen on the current exam .
