Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . A 10 mm small density projecting over the right lower lung without a correlate on the lateral view may represent confluence of shadows , but a small infectious focus can not be excluded . The remainder of the lungs is clear . There is no pleural effusion or pneumothorax . Left volume loss after left lower lobectomy is similar to the prior study . Increased interstitial markings suggest chronic lung disease with emphysema as seen on CT . Bi-apical scarring is unchanged . Cardiac and mediastinal silhouettes and hilar contours are stable . No acute osseous abnormality is identified .
    OUTPUT:
    
New tiny opacity projecting over the right lower lung is likely confluence of shadows , but a tiny infectious focus can not be excluded . Recommend follow up radiographs after treatment .
