Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Unchanged mediastinal and hilar contours . Heart borders are obscured by a minimally increased left lower lung opacity , likely a combination of atelectasis and a moderate left pleural effusion . Right lower lung opacification is likely related to known large right lower lung lesion thought to represent metastatic disease . Stable blunting of the right costophrenic angle , likely represents small pleural effusion versus scarring . Newly evident nodular opacification in the left mid lung without correlate on the ___ CT may represent additional metastatic deposit .
    OUTPUT:
    
Relatively unchanged exam , though new focal nodularity projecting over the left mid lung may represent additional metastatic deposit .
