Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes are present . Heterogeneous opacities at the right lung base are most consistent with an infectious process . Minimal patchy and linear opacity is also noted in the left mid lung field . Heart size is normal . Mediastinal contours are normal . No pleural effusions . No pneumothorax . Given that the right heart border is seen through these opacities , the process is likely in the right lower lobe .
    OUTPUT:
    
Pneumonia at the right lung base , likely in the right lower lobe . Mild patchy opacity in the left mid lung field may also represent a second area of infection .
