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.

Classification

Pneumonias can be classified by:

aetiology
- infection
- aspiration pneumonia
- lipid: lipoid pneumonia
- location
  - community-acquired pnemonia
  - hospital-acquired pneumonia
method of spread (a pathological description)
- bronchopneumonia
- lobar pneumonia
  - multilobar pneumonia
radiographic appearance
- atypical pneumonia
- round pneumonia
