Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The inspiratory lung volumes are low , which accentuates the cardiomediastinal size and limits evaluation of the lung bases . There is no evidence of significant pleural effusion or pneumothorax . A focal consolidation in the left lung base is difficult to exclude . The cardiomediastinal silhouette is unchanged allowing for low lung volumes . The trachea is midline . There is no pulmonary edema or vascular engorgement . The visualized upper abdomen is unremarkable .
    OUTPUT:
    
Equivocal left basilar pneumonia in the setting of low lung volumes .
