Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Since the recent study , a right pleural effusion has decreased in size with only a small residual effusion remaining . There is associated improved atelectasis at the right lung base . A right chest wall mass with associated rib destruction at the levels of the right eighth , ninth and tenth rib levels is again demonstrated , but difficult to precisely measure radiographically . There has been apparent increase in extent of bone destruction in the ribs and adjacent paraspinal regions . Lungs are otherwise remarkable for multiple small pulmonary nodules bilaterally . Cardiomediastinal contours are stable in appearance .
    OUTPUT:
    
1 . Decreased size of right pleural effusion , but apparent increase in extent of bone destruction associated with known right chest wall mass . Consider chest CT for more complete evaluation of the mass , particularly to evaluate for spinal involvement as there was evidence of early cortical destruction of a vertebral body reported on prior CT in ___ . 2 . Multiple pulmonary metastases .
