OBJECTIVE: To observe the presentations and in the @entity1 with @entity39566 ( @entity39566 ) changes of electrophysiology (EP) and magnetic resonance image (MRI) before and after treatment and to analyze their values in diagnosis. METHODS: 10 @entity1 received a series of examinations, including clinical neurological functions, serum @entity2186 and @entity1501 concentrations, spinal cord MRI, peripheral nerve conduction velocity, sensory evoked potential (SEP) and visual evoked potential(VEP). They were followed up for 3 to 36 months. The changes of spinal cord MRI and SEP before and after the treatment were studied. RESULTS: After @entity2186 therapy, all the @entity1 improved,but there were still some @entity3002 left. The lesions could be shown sensitively by EP. The changes of SEP and clinical symptoms correlated with each other. The spinal cord MRIs of most @entity1 showed the lesions objectively, demonstrating primarily long-tape abnormal signals in posterior and lateral columns, iso-intense on T1 and hyper-intense on T2 without contrast. Most lesions were seen at the thoracic cord. The lesions constricted or disappeared when the clinical conditions improved. CONCLUSION: Spinal cord MRI and EP could objectively show the lesions of @entity39566 and the change before and after the treatment. These examinations and the follow-up of disease could be helpful in the diagnosis of @entity39566 .
