    INPUT: AP upright and lateral chest radiographs were obtained . The lungs are well expanded with perhaps mild increase in right pleural effusion which tracks to the apex and along the mediastinal pleural surface . Small left pleural effusion appears unchanged . Though no focal consolidation is seen , right basilar opacities are similar in appearance to that of ___ and could relate to atelectasis or fissural fluid . Increase in interstitial abnormality likely reflect mild pulmonary edema . The heart remains enlarged with a calcified aortic contour and superior vena cava stent noted . Catheter projecting over the right aspect of the vertebral bodies is likely a dialysis catheter terminating in the distal SVC .
    OUTPUT:
    
1 . Slight increase in right pleural effusion with mild pulmonary edema and unchanged left pleural effusion . 2 . Bibasilar opacities are most likely atelectasis or fissural pleural fluid . Infectious process or aspiration is not excluded .
