Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Interval placement of a left - sided internal jugular central venous line with the tip projecting over the expected location of the superior SVC . No pneumothorax . Lung volumes are mildly decreased leading to crowding of the bronchovascular structures . Mild - pulmonary edema and central pulmonary vascular congestion is grossly unchanged . Probable trace right pleural effusion . Bibasilar opacities are noted which likely represent atelectasis . Mild cardiomegaly is unchanged .
    OUTPUT:
    
1 . Status post left IJ CVL placement . No evidence of pneumothorax . 2 . Persistent mild pulmonary edema . 3 . Bibasilar opacities likely reflect atelectasis , although superimposed infection is difficult to exclude .
