Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Again seen are streaky linear areas of opacity projecting over the right lung base which suggests atelectasis as seen on prior studies , possibly minimally more prominent , although this may relate to changes in patient positioning . The appearance of the right hilum and right infrahilar region is stable in this patient with known right hilar mass . The right costophrenic angle is not fully included on the frontal view , but there is no evidence of a large pleural effusion on the lateral view . Left lung is clear . No pneumothorax is seen . The cardiac and mediastinal silhouettes are stable and unremarkable .
    OUTPUT:
    
Stable findings of right hilar mass . Again seen areas of right base atelectasis / scarring , possibly minimally more prominent as compared to the prior study , likely due to potentially minimally worsened right lower lobe atelectasis .
