Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: No significant interval change . Lung volumes remain low bilaterally . The right chest tube projects over the right mid to lower hemithorax with its tip projecting over the right mediastinum . Slight widening of the mediastinum may be projectional but is not changed if not minimally decreased . The heart is top - normal in size . Left moderate pleural effusion is overall unchanged . Atelectasis at the right lung base is also overall unchanged . No pneumothorax . Prominence of pulmonary vasculature is likely secondary to crowding from low lung volumes but is overall unchanged .
    OUTPUT:
    
No significant interval change - persistent moderate left pleural effusion .
