Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A new right internal jugular central venous catheter terminates in the superior vena cava . The cardiac , mediastinal and hilar contours appear unchanged . There is no pleural effusion or pneumothorax . An increased interstitial abnormality suggests pulmonary vascular congestion including Kerley B lines , upper zone redistribution of pulmonary vascularity , and bilateral perihilar fullness . In addition , however , there is increasing confluent right perihilar opacification which is asymmetric and may indicate a superimposed additional process such as pneumonia .
    OUTPUT:
    
1 . Worsening interstitial abnormality suggesting mild - to - moderate pulmonary vascular congestion . More confluent right perihilar opacity . Although an asymmetric pattern of pulmonary congestion could be considered particularly given rapid onset in the same timeframe , coinciding pneumonia should also be considered . 2 . Satisfactory placement of central venous catheter .
