Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a right - sided PICC line in situ , which probably terminates in the upper part of the superior vena cava shortly below the confluence of the brachiocephalic veins , somewhat pulled back from its prior position . However , because of overlying soft tissue attenuation , the catheter is difficult to follow into the mediastinum , so it may terminate somewhat lower in the superior vena cava . The cardiac , mediastinal , and hilar contours appear unchanged . There is no pleural effusion or pneumothorax . The lungs appear clear .
    OUTPUT:
    
PICC line apparently terminating in the upper superior vena cava , although owing to poor visualization of its course in the mediastinum , it may protrude somewhat inferiorly than is apparent from this image . No evidence of acute disease .
