    INPUT: Patient is status post median sternotomy and CABG . Mild cardiomegaly is re - demonstrated . Widening of the superior mediastinum is due to underlying lymphadenopathy , better appreciated on the prior CT . Previous pattern of mild pulmonary edema has improved . Large amount of fluid remains loculated in the minor fissure . Moderate size left and right pleural effusions are re- demonstrated , not substantially changed in the interval . Bibasilar patchy airspace opacities likely reflect areas of compressive atelectasis . No pneumothorax is present . There are no acute osseous abnormalities .
    OUTPUT:
    
Interval improvement in previous pattern of mild pulmonary edema . Moderate size bilateral pleural effusions with a large amount of fluid loculated in the right minor fissure . Bibasilar airspace opacities , likely compressive atelectasis .
