Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are unchanged compared to the prior study . Endotracheal tube and right - sided PICC are unchanged in position . There is persistent and slightly increased airspace opacification seen at the right lung base with partial silhouetting of the right hemidiaphragm . While this may reflect asymmetric pulmonary edema , infection can not be excluded . No definite pleural effusion seen . No pneumothorax .
    OUTPUT:
    
Slight interval increase in the right basal airspace opacity . While this may reflect asymmetric pulmonary edema , the appearances are suspicious for right lower lobe consolidation .
