    INPUT: The cardiac silhouette size is borderline enlarged . Mediastinal and hilar contours are unremarkable . Left PICC has been removed . There is crowding of the bronchovascular structures due to low lung volumes . No overt pulmonary edema is seen . Streaky bibasilar airspace opacities likely reflect atelectasis . No focal consolidation , pleural effusion or pneumothorax is present . There are no acute osseous abnormalities . Multiple clips are demonstrated within the left breast .
    OUTPUT:
    
Low lung volumes with streaky bibasilar airspace opacities likely representative of atelectasis .
