    INPUT: Increased opacification of the left lung with leftward mediastinal shift is suggestive of increased left lung collapse from prior exam . Opacity of the right lung base could represent atelectasis , however can not exclude pneumonia or aspiration in the right clinical setting . Along the lateral border of the right lung , there is again seen a fluid collection adjacent to several rib fractures which are more displaced than on prior exam . This fluid collection is larger than on prior exam and likely reflect ongoing bleeding into the extra-pleural space . There is increased right pleural effusion from prior exam . The cardiomediastinal silhouette can not be well evaluated due to collapse of left lung . Right anterior shoulder dislocation and multiple right - sided chronic rib fractures are again noted .
    OUTPUT:
    
1 . Increases fluid collection along the lateral aspect of the right lung adjacent to several rib fractures which are more displaced than on prior exam , likely representing ongoing bleeding into the extrapleural space . 2 . Interval increase in collapse of the left lung . 3 . Opacity in the right lung base , which could represent atelectasis but can not exclude pneumonia or aspiration in the right clinical setting .
