Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are small to moderate size bilateral pleural effusions , right greater than left . This is obscures the cardiac silhouette making assessment of the cardiac silhouette size difficult . The patient is somewhat rotated . There is diffuse calcification of the trachea and bronchi . No pulmonary vascular congestion is seen . No pneumothorax is clearly present . Bibasilar airspace opacities likely reflect compressive atelectasis , but infection or aspiration are not completely excluded . Moderate cervical lumbar spine , convex to the right is noted .
    OUTPUT:
    
Somewhat limited study due to patient rotation . Small to moderate size bilateral pleural effusions with bibasilar opacities likely reflecting compressive atelectasis . Infection and aspiration at the lung bases however can not be excluded .
