Primary central nervous system vasculitis and headache: Ten themes.

Area of Science:

• Neurology
• Immunology
• Pathology

Background:

• Primary central nervous system (CNS) vasculitis is a group of clinicopathologic disorders characterized by inflammation of cerebral or spinal blood vessels.
• Untreated CNS vasculitis can lead to irreversible neurological injury and disability, highlighting its clinical significance.

Approach:

• Diagnosis relies on a comprehensive evaluation, including tissue confirmation when feasible.
• Treatment strategies involve immune-modulating, suppressive, and targeted immunotherapies to achieve and maintain remission.
• Careful consideration of potential medication adverse effects is essential during treatment selection.

Key Points:

• Headache can be a key indicator of CNS vasculitic involvement.
• CNS vasculitis can be primary (isolated to intracranial/spinal vessels) or secondary to systemic disorders.
• Early suspicion based on clinical presentation and laboratory findings necessitates prompt evaluation to avert cerebral ischemia or infarction.

Conclusions:

• Definitive diagnosis of primary CNS vasculitis requires thorough investigation and, ideally, tissue confirmation.
• Management focuses on inducing and maintaining remission using various immunotherapies while mitigating adverse effects.
• Preventing relapse and irreversible neurological damage are primary goals in managing CNS vasculitis.
