    INPUT: Cardiac silhouette size remains moderately enlarged with a left ventricular predominance . Rightward shift of mediastinal structures due to volume loss in the right lung is similar compared to the prior study . The hila bilaterally remain prominent , but unchanged . Mild pulmonary vascular congestion is new . Bronchiectasis is again demonstrated within the right perihilar region . Patchy opacity is also noted in the left lower lobe , possibly atelectasis . No pleural effusion or pneumothorax is seen . No acute osseous abnormality is detected .
    OUTPUT:
    
Chronic volume loss in the right lung with right perihilar bronchiectasis , as seen previously . Patchy left lower lobe opacity may reflect atelectasis but aspiration or infection is not excluded and correct clinical setting . Mild pulmonary vascular congestion .
