Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: When compared to prior , the previously seen right upper lobe region of consolidation is smaller and more nodular . Vague left upper lung opacity has near completely resolved . There is however new parenchymal opacity in the right lower lobe . There is no effusion or pneumothorax . Cardiac silhouette is mildly enlarged . No acute osseous abnormalities .
    OUTPUT:
    
Right lower lobe consolidation worrisome for pneumonia . Persistent right upper lobe nodular opacities which have decreased since prior exam . While this may represent resolving infection , the possibility of metastatic disease can not be excluded and therefore followup will be necessary after treatment to ensure resolution .
