X-Ray findings

• The most common features on X-ray findings in pneumonia is consolidation.
• This takes in three steps.

1. Opacification starts as a ground glass change.
2. Then the ground glass changes to nodules which contain air spaces.
3. Finally the air nodules coalesce and result in consolidation.

• Rarely a consolidation alone will be present. There may be associated changes which might aid in diagnosing the cause.

1. Pus may be suggestive of an infection.
   1. Tuberculosis: can present with any change
   2. Pneumocystis carinii pneumonia: Peri-hilar opacification
   3. Klebsiella: Bulging fissures with consolidation
   4. Staphylococcal : Cavitation
