[Isolated vasculitis of the central nervous system]

Area of Science:

• Neurology
• Immunology
• Vascular Medicine

Background:

• Vasculitis, inflammation of blood vessels, can affect the central nervous system (CNS).
• Isolated CNS vasculitis is confined to the brain and spinal cord, distinct from systemic forms impacting multiple organs.
• Key symptoms include headache, encephalopathy, focal neurological deficits, and seizures.

Purpose of the Study:

• To outline the diagnostic criteria and therapeutic approaches for isolated CNS vasculitis.
• To differentiate isolated CNS vasculitis from other forms of vasculitis.

Main Methods:

• Diagnostic evaluation involves clinical presentation, exclusion of systemic vasculitis, and specific imaging techniques.
• Cerebral angiography reveals multifocal segmental stenosis of intracranial vessels.
• Magnetic resonance imaging (MRI) shows multiple lesions, often with gadolinium enhancement.

Main Results:

• A definitive diagnosis of isolated CNS vasculitis necessitates a biopsy of leptomeninges and brain parenchyma.
• Angiography and MRI provide supportive evidence but are not diagnostic alone.

Conclusions:

• Isolated CNS vasculitis is a rare but significant cause of neurological disease.
• Diagnosis relies on a combination of clinical, imaging, and histopathological findings.
• Treatment typically involves immunosuppressive therapy with corticosteroids and cyclophosphamide.
