Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is normal . The mediastinal and hilar contours are normal . The pulmonary vasculature is normal . Lungs are clear . There is suture material seen in the anterior left lower lobe as well as increased opacity immediately adjacent to the surgical chain sutures , likely due to postoperative scarring . There is geographically marginated fibrosis in the upper lobes with bilateral upper lobe volume loss . No pleural effusion or pneumothorax is seen . Surgical clips are seen in the left upper abdomen and in the abdomen along the midline .
    OUTPUT:
    
1 . Increased opacity immediately adjacent to the surgical chain sutures in the anterior left lower lobe , most likely due to postoperative scarring . Short - term followup could be obtained if clinically indicated to exclude a pneumonia , especially in the absence of older CXR for comparison . 2 . Geographically marginated fibrosis in the upper lobes with bilateral upper lobe volume loss consistent with previous radiation therapy .
