Summary

Central nervous system (CNS) vasculitis, though rare, presents diverse neurological symptoms. Diagnosis relies on imaging like MRI, autoantibodies, and biopsy, with treatment typically involving steroids and cytotoxic drugs.

Background:

Central nervous system (CNS) vasculitis encompasses various primary and secondary inflammatory conditions affecting blood vessels in the brain and spinal cord.
While infrequent, CNS vasculitis can manifest with a wide spectrum of neurological deficits, including stroke, seizures, and cognitive impairment.
Illicit drug use is also a recognized cause of vasculitis.

Purpose of the Study:

To review the current understanding of CNS involvement in primary and secondary vasculitis.
To discuss diagnostic approaches and management strategies for CNS vasculitis.
To highlight the challenges in diagnosing and treating this rare condition.

Main Methods:

Comprehensive literature review of primary vasculitis (e.g., giant cell arteritis, primary angiitis of the CNS) and secondary vasculitis.
Analysis of diagnostic modalities including neuroimaging (MRI), autoantibodies, and tissue biopsy.
Evaluation of current therapeutic regimens, primarily focusing on immunosuppressive agents.

Main Results:

CNS vasculitis presents with diverse neurological and systemic symptoms, often mimicking other conditions.
Magnetic resonance imaging (MRI) is the most sensitive tool for detecting CNS damage.
Diagnostic features on angiography can be non-specific; autoantibodies and biopsy are crucial.
Effective treatment strategies are limited by a lack of controlled studies, with combined steroid and cytotoxic therapy being common.

Conclusions:

CNS vasculitis requires a high index of suspicion due to its varied presentation.
Multimodal diagnostic approaches are essential for accurate diagnosis.
Standardized treatment protocols are lacking, necessitating individualized therapeutic strategies.
