Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is normal . The mediastinal and hilar contours are unchanged . A moderate to large hiatal hernia is re - demonstrated . The lungs are hyperinflated with emphysematous changes again noted . Ill - defined opacity within the right upper lobe is unchanged , and previously described lesion concerning for neoplasm within the left upper lobe appears relatively unchanged , but better demonstrated on recent CT . Bronchial wall thickening with mild interstitial abnormality within the lung bases likely reflects bronchiolitis , perhaps minimally improved compared to the previous CT . No new focal consolidation , pleural effusion or pneumothorax is seen . There are no acute osseous abnormalities .
    OUTPUT:
    
1 . Bronchial wall thickening with mild interstitial abnormality in the lung bases is minimally improved compared to the previous chest CT and compatible with improving bronchiolitis . 2 . Ill - defined focal opacities in the upper lobes are better demonstrated on the previous CT with the left upper lobe lesion concerning for malignancy on the prior exam . 3 . Emphysema and moderate to large hiatal hernia . 4 . No new focal consolidation .
