    INPUT: There is an irregular nodular opacity in the right upper lobe measuring 1 .8 x 1 .3 cm , which may represent the previously biopsied right upper lobe lesion . There is increased opacification of the right paratracheal stripe , unchanged from the prior chest radiograph . There is no focal consolidation concerning for pneumonia . No significant pleural effusion or definitive pneumothorax is detected . There is hyperexpansion of the lungs and evidence of right upper lobe predominant emphysema as seen on the prior chest CT .

    OUTPUT:
    
1 . No focal consolidation concerning for pneumonia . 2 . 1 .8 cm right upper lobe nodular opacity appears stable at the right lung apex and perhaps even slightly decreased .
