Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Bilateral pleural plaques and irregular , densely calcified pleural calcifications in the left lung , consistent with prior asbestos exposure , are unchanged . Right upper lobe opacity with right hilar elevation and linear arrays of bronchial wall thickening and bronchiectasis is worse since ___ , and is perhaps due to post-radiation fibrosis . However , correlation for history of tuberculosis is warranted . Heart size is normal . The lungs are hyperexpanded with flattened diaphragms , due to emphysema . Due to the preexisting pleural plaques and previously demonstrated breast artifacts , it is difficult to discern if there is a focal consolidation concerning for pneumonia in the mid lung fields . No pleural effusions .
    OUTPUT:
    
1 . Pre-existing pleural plaques and breast tissue artifacts makes it difficult to discern a focal consolidation / pneumonia in the mid lung fields . Routine oblique views are requested for clarification . 2 . Worsened right upper lobe scarring with right hilar elevation and bronchial wall thickening / bronchiectasis may be due to postradiation fibrosis , if there is a corresponding history . Alternatively , close correlation history of tuberculosis is warranted .
