Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are two fiducial markers at the left hilum , where there is again a lobular mass with opacification of the left mid to lower lung , signifying a pleural effusion that is probably moderate to large in size . The right lung remains clear . Findings appear unchanged allowing for differences in technique since a scout view from the prior chest CT .
    OUTPUT:
    
Probably stable abnormalities in the left lung , although radiography is not sensitive for small to moderate but possibly significant changes in the status of malignancy compared to CT .
