Chest X ray in the image shows:Consolidation with air bronchogram
- The left middle zone is white
- Dark lines through the area of white are a good example of air bronchogram
Air bronchogram
- If an area of lung is consolidated it becomes dense and white. If the larger airways are spared, they are of relatively low density (blacker). This phenomenon is known as air bronchogram and it is a characteristic sign of consolidation.
Differential diagnosis of consolidation
- Pneumonia – airways full of pus
- Cancer – airways full of cells
- Pulmonary haemorrhage – airways full of blood
- Pulmonary oedema – airways full of fluid
