Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral views of the chest provided . Lung volumes are low . Compared to prior study from ___ , there is air - space opacity projecting over the lateral mid lung , partially obscured by the pacer battery site , and consolidation due to infection can not be excluded . Bilateral prominence of interstitial markings is grossly unchanged . Two channel pacer positions are unchanged . There is no pleural effusion . There is stable compression deformity of the lower thoracic spine . Chronic deformity with subluxation / dislocation of the right shoulder is again seen . No free air below the right hemidiaphragm is seen .
    OUTPUT:
    
1 . Compared to prior study from ___ , there is stable pulmonary edema . 2 . Airspace opacity underlying the pacemaker battery site is seen projecting over the left mid lung not well evaluated due to partial obscuration by the overlying pacemaker battery , but underlying consolidation due to infection may be present . Consider oblique radiographs for further assessment . 3 . Stable compression deformity of the lower thoracic spine .
