Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart size is within normal limits . The aorta remains unfolded . Pulmonary vascularity is not engorged . A small to moderate size partially loculated right pleural effusion appears increased in size compared to the prior exam . Bibasilar airspace opacities could reflect atelectasis , but infection is not excluded . Small left pleural effusion may be present , though assessment of the left costophrenic angle is obscured due to overlying wires . No pneumothorax is identified . There are no acute osseous abnormalities .
    OUTPUT:
    
Interval increase in size of small to moderate size right pleural effusion , a component of which is loculated laterally . Possible small left pleural effusion , though the left costophrenic angle is not well assessed . Bibasilar airspace opacities could reflect atelectasis but infection can not be excluded .
