Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs remain hyperinflated consistent with underlying emphysema , and biapical pleural scarring is unchanged . Airspace opacity , predominantly within the mid left lung , likely reflects atelectasis , although underlying infection can not be excluded . No lobar consolidation or large pleural effusion . The cardiomediastinal silhouette is within normal limits . A gastrostomy tube projects over the mid left abdomen . Dextroscoliosis centered in the lower thoracic spine is unchanged . PEG tube in the right upper quadrant again noted .
    OUTPUT:
    
Hyperinflated lungs with biapical scarring consistent with underlying emphysema . Predominantly left midlung airspace opacity likely represents atelectasis , although early pneumonia or aspiration can not be excluded . Followup imaging should be considered .
