title: Hemidystonia secondary to cervical demyelinating lesions.
abstract: Hemidystonia is usually associated with a structural lesion in the contralateral basal ganglia. We report a patient with definite multiple sclerosis, according to Poser's criteria, presenting with an acute-onset sustained left hemidystonia. Cranial T2-weighted magnetic resonance imaging (MRI) showed several hyperintense lesions in the centri semiovali and in the periventricular area without basal ganglia involvement. Moreover cervical spinal cord T2-weighted MRI showed two hyperintense lesions in the left posterolateral spine at C2 and C3, and one lesion in the right posterolateral spine at C4 levels. The hemidystonia improved completely after daily treatment with 1000 mg of methylprednisolone, and cervical MRI was performed after the improvement which showed that the lesions had become smaller and less intense. Finally we consider that the hemidystonia may be caused by the cervical spinal cord lesions of multiple sclerosis.
