    INPUT: Lung volumes are low . Heart size remains moderately enlarged . Mediastinal and hilar contours are unremarkable . Crowding of bronchovascular structures is present without overt pulmonary edema . Patchy opacities are seen in the lung bases likely reflective of atelectasis . No definite focal consolidation , pleural effusion or pneumothorax is present . Marked degenerative changes with diffuse idiopathic skeletal hyperostosis is noted in the imaged thoracolumbar spine . Additionally diffuse increased sclerosis of the vertebral bodies is unchanged compared to the prior CT .
    OUTPUT:
    
Low lung volumes with probable bibasilar atelectasis . Diffuse increased sclerosis of multiple vertebral bodies within the imaged thoracolumbar spine , unchanged from the prior CT , and clinical correlation with any history of malignancy is recommended .
