The graver course is one form of malignant multiple sclerosis, with patients reaching a significant level of disability in less than five years from their first symptoms, often in a matter of months. Sometimes Marburg MS is considered a synonym for tumefactive MS, but not for all authors.

Pathogenesis

Marburg MS has been reported to be closer to anti-MOG associated ADEM than to standard MS It has been reported to appear sometimes post-partum

MOG antibody‐associated demyelinating pseudotumor

Some anti-MOG cases satisfy the MS requirements (lesions disseminated in time and space) and are therefore traditionally considered MS cases. After the discovery of the anti-MOG disease this classification is into revision.

Treatment

Historically, acute MS was a fatal disease, with death occurring within a year of onset, often secondary to extensive brainstem demyelination. Treatments include plasma exchange and/or high-dose glucocorticoids(e.g., 1 g/day of methylprednisolone for 3-5 days). Patients that satisfy criteria for MS will be treated with immunomodulatory therapies, often favoring high efficacy monoclonal antibodies.

Prognosis

Marburg variant of MS is an acute fulminant demyelinating process which in most cases progresses inexorably to death within 1–2 years. However, there are some reports of Marburg MS reaching stability by three years.
