Fewer than a hundred cases of paroxysmal dystonia have been described in patients with multiple sclerosis (MS). Even fewer cases of hemidyskinesia triggered by repetitive movements (paroxysmal kinesigenic hemidyskinesia--PKD) have been reported in MS patients. We describe the case of a woman, age 18 years at the onset of MS, and a man age 35 years at the onset of MS, who presented with PKD as the initial symptom. Magnetic resonance images (MRI) of these patients showed different areas of acute lesions possibly related to PKD; MRI of one of the patients demonstrated 1 lesion in the subcortical parietal area and another in the thalamic region and showed 2 lesions in the cervical spinal cord in the other patient.
多发性硬化症(MS)患者中阵发性肌张力障碍的病例描述不到100例。MS患者中由重复性运动触发的半身不自主运动(阵发性运动诱发性半身不自主运动——PKD)的病例报告更少。我们描述了一名女性患者,MS发病时18岁,以及一名男性患者,MS发病时35岁,他们均以PKD作为首发症状。这些患者的磁共振成像(MRI)显示了可能与PKD相关的不同急性病变区域;其中一名患者的MRI显示皮质下顶叶区域有1个病变,丘脑区域有另1个病变,另一名患者的MRI显示颈髓有2个病变。
