Twenty three patients with hemiballism and two with biballism were studied. Ischaemic and haemorrhagic strokes were the cause in most patients. Other causes were encephalitis, Sydenham's chorea, systemic lupus erythematosus, basal ganglia calcifications, non-ketotic hyperglycaemia, and tuberous sclerosis. Neuroimaging studies showed a lesion of the subthalamic nucleus in only six patients. In others, different subcortical structures were involved or the results were normal. Only two patients had "pure" hemiballism. The others had other types of dyskinesias, mainly chorea, which was present in 16 patients. The prognosis was usually good.
对23例偏身投掷症患者和2例双侧投掷症患者进行了研究。大多数患者的病因是缺血性和出血性中风。其他病因包括脑炎、风湿性舞蹈病、系统性红斑狼疮、基底节钙化、非酮症高血糖症和结节性硬化症。神经影像学研究仅在6例患者中显示丘脑底核有病变。在其他患者中,不同的皮质下结构受累或结果正常。只有2例患者患有“纯”偏身投掷症。其他患者有其他类型的运动障碍,主要是舞蹈症,16例患者存在舞蹈症。预后通常良好。
