    INPUT: As compared to prior chest radiograph from ___ , there has been interval placement of a right IJ central venous catheter with its tip terminating in the mid SVC . There is no definite pneumothorax . As before , there is mild enlargement of the cardiac silhouette . Bilateral hilar enlargement is likely due to pulmonary hypertension . The mediastinal contours are otherwise unremarkable . There is mild pulmonary vascular congestion and probable small bilateral pleural effusion . Opacities at the lung bases likely reflect atelectasis , although underlying pneumonia can not be excluded .
    OUTPUT:
    
1 . Right IJ central venous catheter terminates in the mid SVC . No pneumothorax . 2 . Pulmonary edema with bilateral small pleural effusion . Opacities at the lung bases likely reflect atelectasis , however an underlying pneumonia can not be excluded .
