Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right - sided chest tube has been removed . There is increasing opacification of the right lung base with more patchy heterogeneous opacity situated in the right mid lung . There is mild leftward shift of mediastinal structures associated with this appearance that appears new or increased since the prior examination . Aside from vague opacities in the left mid to lower lung which may be due to atelectasis or mild fluid overload , the left lung remains essentially clear . A substantial component of opacification in the right hemithorax is potentially due to pleural effusion , possibly with loculations . Enlargement of the right paratracheal stripe , immediately above the carina suggests that there may be increasing lymphadenopathy , but difficult to compare to the prior studies .
    OUTPUT:
    
1 . Increased opacification in the right hemithorax with leftward mass effect and concern for new right mediastinal lymphadenopathy . Findings may include a pleural effusion on the right , but the appearance is not well assessed with radiography . If needed clinically , chest CT may be helpful to evaluate further . 2 . Vague opacities in the left mid to lower lung , not specific , but mild fluid overload could be considered with atelectasis .
