Marburg’s variant multiple sclerosis (MS) is an acute and aggressive atypical form of MS, leading frequently to death in few months. A 32-year-old man with motor and sensory symptoms suggestive of acute myelopathy, rapidly followed by cerebellar dysfunction and consciousness impairment. Clinical, laboratory and radiological evaluations suggested a central nervous system demyelinating disease. The diagnosis was Marburg’s variant MS, usually leading to death in short time. He underwent different treatments, including steroids, cyclophosphamide, plasma exchange and lastly interferon-beta. The patient reached clinical stability with severe residual disability, persistent after 3 years from onset. This observation suggests that subjects with Marburg’s MS might reach long clinical stability.
