Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The left - sided PICC terminates deep in the right atrium and could be retracted approximately 5 cm to lie in the distal SVC . An ET tube is appropriate position an enteric tube extends into the stomach . No pneumothorax identified . Moderate cardiomegaly is stable . Again seen is an opacity in the left lower lobe obscuring the left hemidiaphragm and left heart border consistent with left lower lung collapse . The opacity at the right base medially is more prominent and a pneumonia can not be excluded in this location . Again seen is the rounded density projecting over the lateral right midzone which when compared to the prior exam appears to lie outside of the lung .
    OUTPUT:
    
1 . Left - sided PICC terminates deep in the right atrium and could be retracted 5 cm to lie in the distal SVC . 2 . The opacity at the right lung base medially appears more prominent and a pneumonia can not be excluded .
