The patchy consolidation in this image is correctly described as being located in the right lower zone
It is possible to determine the consolidation is not in the right upper lobe as it is below the anatomical level of the horizontal fissure
It is not possible to determine if the consolidation is in the right lower or middle lobe – there is no positive silhouette sign present as was the case on the previous page
This image shows a large area of dense consolidation located in the right middle zone – air bronchogram is visible
No single well-defined lobe is affected
Subtle consolidation of the left lower zone with reduced definition of the left hemidiaphragm indicates involvement of a small area of the left lower lobe
The left heart border remains well-defined indicating the consolidation is not in the lingula – part of the left upper lobe
Note: Determining the exact lobar location of consolidation does not usually alter management in the case of suspected pneumonia
