Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear stable . Lung volumes are low . The course of a right - sided PICC line is difficult to follow within the mediastinum due to incomplete penetration of soft tissue structures . It passes at least into the upper superior vena cava , it s tip not visualized on this study . There is probably a small pleural effusion on the left and in any case hazy opacification which could be seen with either atelectasis although potentially pneumonia . There is similar mild perhilar vascular engorgement . However , there has been no significant change .
    OUTPUT:
    
Similar venous hypertension and left basilar opacification . PICC line termination point not well assessed although the catheter can be followed into the upper superior vena cava .
