    INPUT: Minimal bibasilar opacities correspond with atelectasis seen on concurrent CT abdomen and pelvis . No confluent consolidation is identified . There is no large pleural effusion . No pulmonary vascular congestion or interstitial edema is evident . There is no pneumothorax . Mediastinal acontours are within normal limits and unchanged from prior . Mild prominence of the hila bilaterally is likely secondary to large underlying vasculature .
    OUTPUT:
    
Bibasilar atelectasis as confirmed on concurrent CT .
