    INPUT: Moderate enlargement of the cardiac silhouette is re - demonstrated . Atherosclerotic calcifications are noted within the aortic knob . Moderate pulmonary edema is similar to that seen on the previous examination . There are small bilateral pleural effusions , left greater than right , perhaps minimally decreased in the interval . Ill - defined consolidative airspace opacities in the lung bases are re- demonstrated , potentially reflecting a combination of atelectasis and infection or aspiration . No definite pneumothorax is detected on this examination , and a previously noted air-fluid level within the right lung base is not clearly delineated on the current exam .
    OUTPUT:
    
Similar appearance of moderate pulmonary edema and small bilateral pleural effusions , left greater than right . Bibasilar consolidative airspace opacities may reflect a combination of atelectasis and infection or aspiration .
