Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral chest radiographs demonstrate stable cardiomediastinal and hilar contours with a prominent pericardial fat pad , causing increased opacification projecting over the left lower lung . Due to increased right upper lobe volume loss , the previously identified right upper lobe density has become elevated and obscured by overlying rib . In addition , the lesion is less dense and with a siggestion of crescentric lucency along the superolateral aspect , possibly representing cavitation . There is a new vague opacification within the right lower lung which may represent early infectious process .
    OUTPUT:
    
1 . No new pulmonary nodule identified . Right upper lobe volume loss with decreased density of known right upper lobe nodule possibly due to cavitation . Recommend chest CT to further evaluate if warranted clinically . 2 . Focal left lower lobe opacification may represent early infection . ___ placed findings on critical communications dashboard at 3 : 44 pm on ___ .
