Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a catheter external to the patient overlying the upper right chest extending across the midline . A previously seen PICC line has been removed in the interval . Diffuse bronchiectasis within the lung bases , right greater than left , appears similar to prior radiographic and CT examinations . However , on the lateral view , there is increased density projecting over the spine , which is concerning for superimposed infection given patient 's clinical history . This likely correlates with subtle increased density in the right lung base on the frontal view . Upper lungs remain clear . There is no pneumothorax . Cardiomediastinal and hilar contours are within normal limits and unchanged .
    OUTPUT:
    
1 . Diffuse basilar bronchiectasis , right greater than left , unchanged from prior . 2 . Increased right lower lobe opacity raises concern for acute infection
