Since the cardiac border can mostly be discerned , the abnormality is suspected to at least predominantly reside in the right lower lobe .
    OUTPUT:
    
Findings consistent with pneumonia in the right lower lobe . Follow - up radiographs are recommended following treatment in order to ensure resolution .
