Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are hyperinflated . Increased right infrahilar opacity could reflect aspiration and pneumonia . There appears to be mild peribronchiolar thickening . The minor fissure with is depressed , suggesting some degree of atelectasis in the right lung . Streaky opacities in the left lower lung may reflect atelectasis . No pleural effusion or pneumothorax . Background hyperlucency of the lungs suggests emphysema . An approximately 5 mm the opacity in this periphery of the right midlung could be a vessel on and , however pulmonary nodule can not be excluded . Probable 4 - mm calcified granuloma in the left periphery of the lung .
    OUTPUT:
    
1 . Right lower lobe opacity could reflect pneumonia in the appropriate clinical situation . Close interval follow - up after treatment is recommended . This patient could benefit from a non-emergent Chest CT if he has not had any before . 2 . Background emphysema . 3 . Possible 5 mm right peripheral mid lung nodule versus a vascular marking . Correlate with any prior imaging .
