    INPUT: Frontal and lateral views of the chest were obtained . Again , there is opacification of the right base posteriorly and laterally consistent with pleural thickening seen on previous CT . Opacity is slightly less prominent on the current study as compared to the prior . There is persistent blunting of the right costophrenic angle , again possibly due to combination of pleural thickening and a small pleural effusion . No new focal consolidation is seen . There is no evidence of pneumothorax . The cardiac and mediastinal silhouettes are unremarkable . Degenerative changes are seen on spine .
    OUTPUT:
    
No significant interval change .
