If a person has pneumonia, the alveoli in one or both lungs fill with pus and fluids (exudate), which interferes with the gas exchange.
This is sometimes known as ‘consolidation and collapse of the lung’.

It can result from a large number of pathogens, which include: If a necrotizing infection is suspected and CT evaluation is required, it may be better to give contrast as it allows appreciation of low attenuation and non-enhancement within the necrosed portions.
CT imaging may show distinct areas of low attenuation with decreased parenchymal enhancement (representing liquefaction .
For example, pulmonary infarction often results in consolidation without air bronchograms because of blood filling the bronchi.
In patients with bronchopneumonia, bronchi may be filled with mucus or pus.
The term "pasteurellosis" is often still applied to mannheimiosis, although such usage has declined.
With some causes of consolidation, air bronchograms may not be visible.
This usually occurs because of central bronchial obstruction (e.g., by cancer or mucus) or filling of bronchi in association with the underlying pathologic process.
