Extensive bilateral opacities are consistent with widespread pulmonary metastatic disease , with mild improvement of the left lung . There is a new small to moderate right pleural effusion . No obvious focal consolidation is identified , although a small focus would be difficult to identify given background parenchymal opacities . The visualized upper abdomen is unremarkable .
    OUTPUT:
    
1 . No obvious focal consolidation to suggest infection , though difficult to exclude given extensive background parenchymal opacities . 2 . Small to moderate right pleural effusion .
