1
Q
What does the label “diffuse lung disease” actually refer to?
A
- Cough
- Dyspnoea
- X-ray showing diffuse lung involvement
2
Q
What are acute pathological processes that could cause an diffuse lung pattern on x-ray?
A
- Water - e.g. APO
- Inflammation - inhalation injury, acute drug toxicity, acute infection
- Blood - diffuse leakage e.g. vasculitis
3
Q
