    INPUT: Moderate enlargement of the cardiac silhouette is unchanged . Atherosclerotic calcifications of the aortic knob are again noted . The mediastinal contour is similar . There is mild pulmonary edema , not substantially changed in the interval . Hazy opacities in both lung bases , more so on the left , likely reflect small layering bilateral pleural effusions . Patchy bibasilar opacities likely reflect compressive atelectasis . No pneumothorax is clearly evident . There are no acute osseous abnormalities .
    OUTPUT:
    
Mild pulmonary edema , not substantially changed in the interval with small layering bilateral pleural effusions and bibasilar atelectasis .
