    INPUT: Lung volumes are low . The heart size is moderately enlarged . The aorta is tortuous and diffusely calcified . There is crowding of the bronchovascular structures but no overt pulmonary edema is seen . Streaky left basilar opacity likely reflects atelectasis . Right apical calcifications are unchanged . No large pleural effusion or pneumothorax is identified . Diffuse demineralization of the osseous structures is noted .
    OUTPUT:
    
Low lung volumes with minimal left basilar atelectasis .
