Fulminant multiple sclerosis versus autoimmune encephalitis: A case report

Area of Science:

• Neurology
• Immunology

Background:

• Fulminant multiple sclerosis (MS), or Marburg variant (MVMS), requires prompt diagnosis and treatment to improve patient outcomes.
• Seronegative autoimmune encephalitis (AIE) presents clinical similarities and can be indistinguishable from fulminant MS.

Observation:

• This case study details the clinical course of a patient with suspected MVMS or AIE.
• The study highlights the diagnostic challenges in differentiating between these two neurological conditions.

Findings:

• Early intervention is critical for managing fulminant MS and improving prognosis.
• Similarities in clinical presentation necessitate careful differential diagnosis between MVMS and AIE.
• Rituximab demonstrated efficacy in this patient following plasmapheresis, suggesting a potential therapeutic role.

Implications:

• The findings underscore the importance of timely diagnosis and treatment in severe neurological conditions.
• Shared management protocols may be applicable to both fulminant MS and AIE in certain clinical scenarios.
• Rituximab may be a valuable treatment option for patients with fulminant MS or AIE unresponsive to initial therapies.
