- Document
- Original educational diagram
- Scope
- No real examination simulated
- Takeaway
- Describe before attributing; an arterial stenosis or CSF abnormality alone does not prove vasculitis.
Diagram description
Concept cards distinguish groups of mechanisms. No MRI slice, synthetic lesion or patient data is displayed.
Reasoning
Describe before attributing; an arterial stenosis or CSF abnormality alone does not prove vasculitis.
Clinical comparison
Interpret the findings together and investigate competing explanations when data do not agree.
Pitfalls and limits
This is a conceptual educational aid, not an authentic examination, a complete diagnostic rule or an individual prescription. See the cited sources and full French statement of limitations.
Take-home message
Describe before attributing; an arterial stenosis or CSF abnormality alone does not prove vasculitis.
