    INPUT: Again seen patchy opacity in the left lung base could be due to atelectasis , though underlying consolidation is not excluded . There is a rounded opacity at the right lung base measuring 1 .3 cm which may represent nipple shadow , can be confirmed with repeat with nipple markers . Blunting of the costophrenic angles may be due to trace pleural effusions . The cardiac silhouette remains mildly enlarged . Calcified left hilar nodes again seen . The mediastinal contours are stable .
    OUTPUT:
    
Small bilateral pleural effusions . Bibasilar opacities may represent combination of effusion and atelectasis , although underlying early consolidation can not be excluded . 1 .3 - cm nodular opacity projecting over the right lung may represent nipple shadow , this can be confirmed with repeat with nipple markers . Stable cardiomediastinal silhouette . Calcified left hilar node again seen .
