Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right - sided lateral and posterior pleural opacity corresponds to areas of pleural thickening on prior PET - CT of ___ , likely related to previous history of talc pleurodesis . There is associated mild volume loss suggesting a component of fibrothorax , and there may be a small residual amount of pleural fluid , but this has not appreciably changed from prior radiographs . Reticular opacities in the right mid and lower lung are slightly more conspicuous than on the prior study . Left lung and pleural surfaces are clear . Cardiomediastinal contours appear unchanged . High - grade compression deformity in lower thoracic spine is also unchanged .
    OUTPUT:
    
1 . Chronic right pleural thickening . 2 . Slight worsening of reticular pattern in right mid and lower lung region . Review of prior PET - CT from ___ demonstrates diffuse septal thickening in the right lung , which likely corresponds to this radiographic pattern . The etiology is uncertain but could potentially be due to lymphoma . Drug - induced lung disease is more typically bilateral . An acute infectious process superimposed on chronic interstitial abnormalities is an additional consideration , and followup radiographs may be helpful in this regard if warranted clinically .
