RESUMO
Objective To evaluate the clinical manifestations and magnetic resonance imaging(MRI) features of the clinically isolated syndrome(CIS) of the spinal cord.Methods MRI features and expanded disability status scale(EDSS) score in 63 patients with multiple sclerosis(MS) showed early clinical manifestations of spinal CIS were retrospectively analysed.Results 52.9% of MS patients in the early performance was the spinal CIS,88.9% was acute or subacute onset,42.9% of the initial symptoms was isolated sensory dysfunction,and 54.9% had cervical spinal cord involvement.The first MRI positive rate was 91.1% and 35.3% presented with "multifocal" plagues.81.7% of the MRI lesions were not more than two vertebral segments,and 89.0% in the axial diameter of the spinal cord did not exceed 1/2.The number,volume and area of MRI lesions at baseline confirmed the positive correlation with EDSS at diagnosis of MS.Corticosteroid therapy before and after the EDSS score was of a significant difference(P= 0.003).Conclusion Spinal CIS often occurs in cervical spinal cord with acute or subacute onset,and incomplete spinal cord injury.MRI may detect "multifocal" plagues.Quantitative MRI is valuable for the assessment of prognosis.Early intravenous corticosteroid therapy can be an effective way to ease symptoms.
