Consolidation - Right lower zone

  • 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

Consolidation - Multiple zones

  • 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

RMZ pneumonia and pleural effusion

  • An area of consolidation is seen in the right middle zone (RMZ) – air bronchogram is visible
  • Below this there is an area of whiteness due to a parapneumonic effusion – no air bronchogram is visible in this area
