Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A portable frontal chest radiograph demonstrates unchanged mild cardiomegaly and low lung volumes . The right lower lung opacity has increased , most likely due to progression of the right lower lobe consolidation , but could be due to slightly lower lung volumes . In the case of progression of the consolidation , repeat aspiration can not be differentiated from pneumonia . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
Increasing right lower lung opacity is most likely due to progression of the right lower lobe consolidation , and repeat aspiration can not be differentiated from pneumonia . It is less likely due to lower lung volumes . Clarification with repeat PA and lateral chest radiographs with an emphasis on inspiration may be helpful in determining true progression of the consolidation as opposed to changes due to low lung volumes . These findings were discussed via telephone by Dr . ___ with Dr . ___ at ___ on ___ .
