    INPUT: Cardiac , mediastinal and hilar contours are unremarkable . Pulmonary vasculature is normal . Elevation of the right hemidiaphragm is unchanged and attributable to a large hypodense lesion within the right lobe of the liver as seen on recent CT . Patchy opacities in the lung bases , more so on the right , are compatible with areas of atelectasis , and appear similar compared to the prior CT . No pleural effusion or pneumothorax is seen . There are no acute osseous abnormalities .
    OUTPUT:
    
Bibasilar atelectasis . Continued elevation of the right hemidiaphragm due to known right hepatic lobe hypodense lesion as seen on recent CT .
