    INPUT: Frontal and lateral views of the chest demonstrate stable mildly prominent cardiac silhouette , accentuated by low lung volumes . The mediastinal and hilar contours are otherwise unremarkable . The lungs are clear with the exception of trace if any bibasilar atelectasis . Mild blunting of the left costophrenic angle may be related to presence of a pericardial fat pad . There is no pneumothorax or vascular congestion . Minimal multilevel lower thoracic spondylosis is present .
    OUTPUT:
    
No definite evidence of acute cardiopulmonary process such as pneumonia . Mild left costophrenic blunting likely due to pericardial fat pad . No pneumothorax .
