Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right - sided internal jugular central venous catheter is again seen , unchanged in position , terminating at the cavoatrial junction . There is a persistent small left pleural effusion with overlying atelectasis . There may be a trace right pleural effusion . The previously seen coarse bilateral interstitial markings have decreased in prominence in the interval , although do remain similar to prior . There is slightly increased opacity in the region of the right lung base which may relate to pulmonary edema , although superimposed infectious process is not excluded . There is varus angulation of the right humeral head due to a prior humeral neck fracture .
    OUTPUT:
    
Bilateral pleural effusions , left greater than right . Interval decrease in conspicuity of diffuse prominence of coarse interstitial markings . Slight area of opacity at the right lower lung appears improved as compared to priors and may relate to pulmonary edema , however , superimposed infection is difficult to exclude .
