In this case report we describe the case of a 24 year-old female with a fulminant demyelinating disease of white matter. Disease progression was most probably consistent with the Marburg variant (malignant form) of multiple sclerosis with rapid deterioration of the patient's clinical condition, including bulbar symptoms and epileptic paroxysms and ending with persistent coma and tetraparesis, over the course of 6 months from first symptoms. Repeated Magnetic Resonance Imaging (MRI) examination showed progression of multiple demyelinating lesions culminating in a contiguous focal disorder of the white matter extending both supratentorially and infratentorially. The serial MRI changes closely mapped the deterioration in the patients clinical status. Our patient showed no response to repeated pulse corticotherapy, administration of intravenous immunoglobulins, serial plasmapheresis, and combined high-dose pulse immunosuppression (specify what was used here) and mitoxantrone.
