Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right - sided internal jugular venous catheter terminates in the mid superior vena cava . Widespread opacification is seen in both lower lungs , more extensive on the right than left . The likely etiology is a combination of substantial bilateral pleural effusions and associated extensive atelectasis in the lower lungs . The pleural effusions are moderate on the left and perhaps large on the right side . Upper lungs appear clear but with attenuated irregular lung markings suggesting there may be emphysema . The aortic arch is calcified . The main pulmonary artery contour is mildly prominent . Although its contours are not well delineated , the heart is probably at the upper limits of normal size . Effacement of the right acromiohumeral interval suggests rotator cuff pathology . The bones are probably demineralized .
    OUTPUT:
    
Opacification of the lower lungs , greater on the right than left , probably reflecting pleural effusions and associated atelectasis , although an infectious process is hard to exclude . Regular lung markings and architecture suggesting there may be emphysema .
