Summary

Central nervous system vasculitis is a rare complication of rheumatoid arthritis. This case highlights the importance of neuroimaging in diagnosing this condition, even with normal initial tests.

Area of Science:

  • Neurology
  • Rheumatology
  • Immunology

Background:

  • Rheumatoid arthritis (RA) is a chronic autoimmune disease primarily affecting joints.
  • Central nervous system (CNS) involvement in RA, such as vasculitis, is uncommon.
  • Early diagnosis and treatment are crucial for managing CNS complications.

Observation:

  • A 55-year-old woman with a 7-year history of seropositive, nodular rheumatoid arthritis presented with neurological symptoms.
  • Magnetic resonance imaging (MRI) revealed multifocal white matter abnormalities suggestive of vasculitis.
  • Cerebrospinal fluid (CSF) studies and cerebral angiography were normal, complicating the diagnosis.

Findings:

  • Despite normal initial investigations, cerebral vasculitis was diagnosed based on MRI findings.

  • Treatment with glucocorticoids and azathioprine resulted in a stable condition for 14 months.
  • Postmortem examination confirmed CNS vasculitis and chronic ischemic changes.

    • Implications:

    • This case underscores the utility of advanced neuroimaging in diagnosing CNS vasculitis in RA patients.
    • It emphasizes the need for a high index of suspicion for vasculitis in RA patients with unexplained neurological deficits.
    • Prompt immunosuppressive therapy may improve outcomes in CNS vasculitis associated with rheumatoid arthritis.
