    INPUT: A subpleural mass in the right upper thorax is compatible with the known expansile metastatic lesion arising from the second right rib seen in the prior CT . Based on plain films , it appears larger when compared to prior and there is more destruction of the second rib . A second sclerotic lesion in the left posterior ninth rib was also better seen on prior CT . No rib fracture is identified . The lungs are well - expanded . No focal opacities are identified . There are small bilateral pleural effusions . There is no pneumothorax . Cardiomediastinal and hilar contours are unremarkable .
    OUTPUT:
    
1 . Small bilateral pleural effusions . No evidence of pneumonia . 2 . Expansile metastatic lesion of the right second rib appears larger , and the sclerotic lesion of the posterior left ninth rib are better seen in prior CT .
