Summary
Infectious vasculitis affecting the central nervous system can cause stroke and aneurysms. Neuroimaging is key to diagnosing these challenging inflammatory conditions caused by various pathogens.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Vasculitis is a complication of CNS infections.
- It can lead to stroke, transient ischemic attack, and aneurysms.
- Diagnosis is challenging due to overlapping symptoms with non-infectious vasculitis.
Purpose of the Study:
- To review the imaging features of infectious vasculitis.
- To cover bacterial, viral, fungal, and parasitic causes.
Main Methods:
- Review of neuroimaging findings in infectious central nervous system vasculitis.
Main Results:
- Infectious agents cause vasculitis via direct endothelial infection or immune response.
- Neuroimaging identifies inflammatory changes characteristic of intracranial vasculitis.
Conclusions:
- Infectious vasculitis presents diagnostic challenges.
- Neuroimaging is crucial for identifying inflammatory changes in the brain's blood vessels.
