Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison to the chest radiograph obtained 2 hours prior , there is been interval placement of a left - sided IJ central venous catheter which terminates near the confluence of the left brachiocephalic vein and SVC . An enteric tube terminates within the gastric body . Bibasilar opacities likely reflect atelectasis , although there is some asymmetry with increased opacification at the left base and a small pleural effusion , possibly suggesting the presence of a pneumonia . Mild cardiomegaly is mildly increased , but without pulmonary vascular congestion or pulmonary edema . Cardiomediastinal hilar silhouettes are otherwise normal .
    OUTPUT:
    
A left - sided central venous catheter terminates at the junction of the SVC and left brachiocephalic vein . Minimally increased bibasilar atelectasis or alternatively a developing pneumonia .
