Fulminant multiple sclerosis versus autoimmune encephalitis: A case report

Abstract

Key Clinical MessageThis case highlights the importance of early diagnosis and treatment in prognosis of fulminant multiple sclerosis, and its similar management with autoimmune encephalitis in some clinical settings, in which these diseases are indistinguishable. This case also supports the use of rituximab in these patients with an adequate response to plasmapheresis.AbstractEarly diagnosis and treatment of fulminant multiple sclerosis (MS), also known as Marburg' or malignant variant of MS (MVMS), is of great value in reducing morbidity and mortality. Seronegative autoimmune encephalitis (AIE) is very similar to, and sometimes indistinguishable from, fulminant MS. However, the acute and long-term management of the two diseases is often the same. This article describes the clinical course of a patient suspected of having MVMS or AIE and the challenges of their differential diagnosis and management.
