    INPUT: Heart and mediastinum are normal . In the right upper lobe laterally overlying the fifth rib posteriorly , a nodule is present measuring 11 mm . Immediately adjacent , a further nodule is seen , both of which appear to have some calcium within them . This likely represents some old granuloma , but comparison with prior chest x-rays if available should be made . Elsewhere , the lung fields appear clear , the costophrenic angles sharp .
    OUTPUT:
    
Right lung nodule , probably old granuloma but comparison with prior chest x-ray is necessary with none available CT should be performed .
