    INPUT: Previously seen midline tracheostomy is no longer seen . There has also been interval removal of a left - sided IJ venous catheter . A right - sided PICC is seen , distal aspect not well appreciated on this study due to overlying opacity , but does appear to course into at least the superior SVC . Dual lead left - sided pacemaker is again seen with leads extending to the expected positions of the right atrium and right ventricle . There is interval increase in bilateral , right greater than left pulmonary opacities , which given history , likely due to slight asymmetric pulmonary edema , however , superimposed infectious process is not excluded . There is a small right pleural effusion . The left costophrenic angle is not well seen and there may be a trace left pleural effusion . The cardiac and mediastinal silhouettes are stable .
    OUTPUT:
    
Interval increase in bilateral , right greater than left , pulmonary opacities , which given history , likely due to slight asymmetric pulmonary edema , however , superimposed infectious process is not excluded . Small right pleural effusion and possible trace left pleural effusion .
