Pneumonia is a general term in widespread use, defined as infection within the lung. It is due to material, usually purulent, filling the alveoli.

Terminology

Pneumonia is in contrast to pneumonitis, which is inflammation of the pulmonary interstitium. Of note, some of the interstitial lung diseases are termed pneumonia rather than pneumonitis. The term consolidation is often erroneously used as a synonym for pneumonia.

Classification

Pneumonias can be classified by:

aetiology
method of spread (a pathological description)
- bronchopneumonia
- lobar pneumonia
  - multilobar pneumonia
radiographic appearance
