    INPUT: Since the prior exam , there is an increased right pleural effusion with associated right basilar opacity . Additionally , obscuration of the left costophrenic angle is likely due to a small effusion and atelectasis . There is no overt pulmonary edema . The apices of the lungs are clear . There is no pneumothorax . The mediastinal contour is normal . The heart size is moderately enlarged , and unchanged from prior exams .
    OUTPUT:
    
1 . Small bilateral pleural effusions , greater on the right than the left . 2 . Bibasilar opacities , likely atelectasis . In the proper clinical setting , an infection would be difficult to completely exclude . 3 . Stable cardiomegaly .
