    INPUT: Moderate right pleural effusion has increased in size since the previous study and has a configuration suggesting possible partial loculation . Cardiomediastinal contours are stable in appearance . More confluent opacity is present in the left perihilar region and to a lesser extent in the left retrocardiac area . Right basilar atelectasis is present adjacent to the above - described effusion . Diffuse osseous changes of renal osteodystrophy are present in the spine .
    OUTPUT:
    
1 . Interval increase in right pleural effusion , now moderate in size and possibly partially loculated . 2 . Diffuse interstitial edema . 3 . Confluent left juxtahilar opacities which could reflect asymmetrical edema , but followup radiographs are suggested after dialysis to exclude an infectious process in this region .
