stages of empyema

Q: There are how many stages of pleural empyema? 

Answer: 3

There are three stages of pleural (or any) empyema 

  • stage 1 is an exudative phase 
  • stage 2 is when frank pus is visible 
  • stage 3 is the organization phase 
Clinical relevance: As empyema progressed towards late stage 2 and 3, the surgical consultation should be obtained.
