    INPUT: There is a 1 .6 x 2 .9 cm focal , oval opacity at the base of the right lung , which most likely represents evolution of a lytic rib lesion , now with increased sclerosis . The heart is mildly enlarged and the hilar contours are normal . The pleural surfaces are clear without effusion or pneumothorax . Also seen is a partial vertebroplasty along the right side of a lower thoracic vertebral body , unchanged in appearance .
    OUTPUT:
    
1 . Right lower lung opacity most likely represents increasing sclerosis associated with a lytic rib lesion and possibly healing pathological fracture . 2 . No evidence of acute cardiopulmonary process .
