Tumefactive demyelinating lesions spectrum disorders and the potential role of contemporary disease modifying treatments: a case report

Abstract

Marburg disease is a fulminant variant of multiple sclerosis (MS), in which the diagnosis may be particularly difficult and with high rates of mortality. We describe the case of a women with a clinical picture, radiographic features, and neuropathological findings consistent with the classical descriptions of Marburg disease. Initially, our patient did not improved with the acute phase treatments but later showed a good response to natalizumab (NTZ) treatment. This report highlights not only the utility of brain biopsy in the accurate diagnosis of this challenging condition but also the potential role of NTZ as an effective therapeutic option.
