Imaging of Vasculitis Associated with Systemic Disease

Area of Science:

• Neurology
• Radiology
• Immunology

Background:

• Vasculitis involves blood vessel wall inflammation.
• Classification depends on clinical, histological, and imaging features.
• Central nervous system vasculitis presents diagnostic challenges.

Purpose of the Study:

• To review neuroimaging hallmarks of central nervous system vasculitis.
• To associate these findings with prevalent systemic diseases.
• To identify diagnostic pitfalls and confounders.

Main Methods:

• Literature review of neuroimaging in CNS vasculitis.
• Analysis of imaging findings in common systemic vasculitides.
• Discussion of differential diagnoses and confounding factors.

Main Results:

• Specific neuroimaging patterns are associated with different systemic vasculitides.
• Key findings include vessel wall thickening, stenosis, and enhancement.
• Mimics and confounders can complicate diagnosis.

Conclusions:

• Neuroimaging is crucial for diagnosing CNS vasculitis.
• Understanding disease-specific patterns aids diagnosis.
• Awareness of pitfalls improves diagnostic accuracy.
