Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes resulting crowding of the bronchovascular structures . There is no evidence of focal consolidation , pleural effusion , pneumothorax , or pulmonary edema . The cardiomediastinal silhouette is within normal limits with mild tortuosity of the thoracic aorta . Prominence to the right extra-thoracic soft tissues is likely due to hematoma as seen on the concomitant CT . Known small right pleural effusion is seen to better detail on that study .
    OUTPUT:
    
Right Chest wall hematoma and small right pleural effusion , both more fully evaluated by outside CT exam .
