Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right - sided PICC line terminates at the cavoatrial junction . The heart is mild to moderately enlarged . There is a similar opacity in the right lower lung obscuring the right hemidiaphragm . It is difficult to exclude small pleural effusions , although there are no definite effusions . Superimposed on the prior process is prominent indistinct pulmonary vascularity that is increased suggestive of a mild to moderate pulmonary vascular congestion . There is no pneumothorax . Right - sided rib deformities appear unchanged .
    OUTPUT:
    
Persistent right lower lung opacity worrisome for pneumonia . Superimposed diffuse but predominantly central opacification , which is not entirely specific but most suggestive of pulmonary vascular congestion .
