Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is top normal . The aorta is diffusely calcified . Mediastinal and hilar contours are unchanged . Multifocal interstitial opacities with associated bronchiectasis and bronchial wall thickening are again noted and reflective of chronic ___ infection , as assessed on the previous CT . There may be minimal new patchy ill - defined opacities within both mid lung fields , which could reflect superimposed acute infection . Lungs remain hyperinflated . Biapical scarring is again demonstrated . No new focal consolidation , pleural effusion or pneumothorax is identified . Pulmonary vasculature is not engorged . Blunting of the costophrenic angles bilaterally likely reflect chronic pleural thickening . Clips in the right upper quadrant of the abdomen are again noted along with pneumobilia .
    OUTPUT:
    
Chronic diffuse interstitial abnormality with associated bronchiectasis compatible with known chronic ___ infection . There may be minimal new patchy ill - defined opacities within both mid lung fields which could suggest superimposed acute infection .
