    INPUT: Linear scarring within the right upper lobe and within the left lung base appears unchanged compared to multiple prior examinations . Chain suture material in the right mid peripheral lung is unchanged from prior . There is mild interstitial prominence with possible peripheral septal thickening at the right lung base which may reflect minimal amount of pulmonary edema . Blunting of the bilateral costophrenic angles is unchanged from multiple prior examinations and may reflect chronic pleural thickening or small effusions . There is no pneumothorax . Cardiomediastinal and hilar contours are within normal limits . No new focal consolidation is identified .
    OUTPUT:
    
1 . Possible minimal interstitial pulmonary edema . 2 . Stable scarring in the right upper lobe and left lower lobe . 3 . Unchanged chronic pleural thickening or possibly small chronic effusions .
