Acute- and insidious-onset myelopathy of undetermined aetiology: contribution of paraclinical tests to the diagnosis of multiple sclerosis

摘要: Brain magnetic resonance imaging (MRI), multimodality evoked potentials (EPs) and cerebrospinal fluid examination were performed in 42 patients with myelopathy of undetermined aetiology order to detect abnormalities usually related multiple sclerosis (MS). Patients divided into three groups: insidious-onset only motor signs (group A; 11 patients), both sensory B; 18 patients) acute-onset C; 13 patients). Multiple brain MRI lesions found (2 group A, B 3 C). Another 7 had a single white-matter lesion. Visual EPs abnormal 21 brain-stem auditory 12 patients. Paraclinical tests supported the diagnosis MS 25 (60%) by showing subclinical abnormalities. Oligoclonal bands 16 these The findings strongly suggest B.
