Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is stable moderate cardiomegaly . There is a right - sided IJ which terminates in the mid SVC . There is a left - sided pacemaker . Again opacification of the right base medially persists with some obscuration of the right hemidiaphragm . This could reflect merely crowding of vessels ; however , pneumonia should be considered in the appropriate clinical setting . This , however , appears overall stable compared to the prior exam . Again seen is bibasilar atelectasis as well as a small right pleural effusion . There is mild right pulmonary edema . The hilar and mediastinal contours appear stable . There is no pneumothorax . The visualized osseous structures are unremarkable .
    OUTPUT:
    
1 . Opacification at the medial right lung base overall stable compared to the prior exam . This may reflect crowding of vessels however an infectious process should be considered in the appropriate clinical setting . 2 . Mild right pulmonary edema .
