Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size is normal . The aorta remains tortuous . There is mild pulmonary vascular engorgement but no overt pulmonary edema is demonstrated . Streaky opacities in the lung bases likely reflect atelectasis . Minimal blunting of the costophrenic angles posteriorly appears unchanged , compatible with trace bilateral pleural effusions . There is no pneumothorax . Partially imaged is an aortic stent graft within the upper abdomen .
    OUTPUT:
    
Mild pulmonary vascular engorgement and trace bilateral pleural effusions .
