Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The heart is moderately enlarged . The interstitium is prominent including Kerley B lines suggesting mild pulmonary edema . Streaky left mid lung opacities may alternatively be due to atelectasis , however . The left posterior lower lobe appears opacified , which could be seen with coinciding pneumonia or potentially atelectasis . An element of volume loss in the left lower lobe including depression of the major fissure and slight elevation of the left hemidiaphragm . A small pleural effusion is probable on the left and difficult to completely exclude on the right . Fissures are thickened . The bones are probably demineralized . There is incompletely characterized loss in height among several mid - to - lower thoracolumbar vertebral bodies including a moderate mid - to - lower thoracic compression fracture , age indeterminate , although there is no reason to think that this is likely to be recent in onset .
    OUTPUT:
    
1 . Focal opacification in the left lower lobe with volume loss . This appearance could be seen with clinically suspected pneumonia , versus atelectasis . 2 . Findings also suggesting mild pulmonary edema . 3 . Thoracolumbar compression deformities .
