Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear stable . Generalized opacification has improved somewhat suggesting reduction in fluid overload , but on this examination there is a developing opacity projecting over the right lower lung , probably in the right lower lobe . There is still a substantial nodular focus projecting over the left mid lung and possibly a second one projecting nearby . The right mid-to - lower lung is difficult to assess for any possible nodules .
    OUTPUT:
    
Reduction in generalized opacification suggesting fluid overload , but developing right lower lung opacity suggesting pneumonia . Persistent nodular focus projecting over the left mid lung and possibly a second one ; if these were confirmed to represent true pulmonary nodules rather than summation artifact and / or a nipple shadow , then these might potentially represent new metastatic disease .
