No pleural effusion or pneumothorax is appreciated . No rib fracture is seen .
    OUTPUT:
    
Interval resolution of right basilar opacity with no acute cardiopulmonary process . No rib fracture is identified . Consider dedicated rib series with radiopaque BB at the site of pain if clinical concern persists .
