Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is normal in size . The mediastinal and hilar contours appear within normal limits . There is no pleural effusion or pneumothorax . Mild degenerative changes are noted along the lower thoracic spine . Along the right lower lateral chest wall , there is convex pleural thickening measuring up to 25 mm as measured on the frontal radiograph . This appearance raises concern for a pleural - based mass , although it may reflect loculated effusion or area of scarring . Comparison to prior radiographs would be helpful and particularly if long - term documentation of stability of this appearance is not possible , chest CT , preferably with intravenous contrast is suggested to assess further .
    OUTPUT:
    
1 . No evidence of acute cardiopulmonary disease . 2 . Substantial focal right lateral pleural thickening ; differential considerations include both benign and malignant processes . Correlation to prior radiographs is recommended if available . Particularly if long - term stability of this appearance can not be established by comparison to prior imaging then chest CT is recommended to assess further when clinically appropriate .
