Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal , and hilar contours appear unchanged . The heart is at the upper limits of normal size . There is no pleural effusion or pneumothorax . There is an entirely unchanged patchy opacity in the right upper lobe since the prior radiographs with volume loss in the right upper lobe and streaky opacification radiating from the upper right hilum , the latter better appreciated on the lateral view . This appearance is stable and most suggestive of sequelae of prior tuberculosis . Streaky right mid lung opacity is compatible with minor unchanged scarring .
    OUTPUT:
    
Findings suggestive of prior tuberculosis with stable associated opacities in the right upper lobe .
