It is widely believed that hemiballismus and chorea are suggestive of a basal ganglia subthalamic nucleus lesion; however, this not a rule. We report the case of a 63-year-old male with complaints of slurred speech, increased movement of the left half of his body, and headache. He had diabetes, hypertension, and a past medical history of stroke with residual weakness over the right side of his body. The patient developed the sudden onset of irregular, large amplitude, increased involuntary movements of his left upper and lower limbs with a flinging pattern. His blood sugar and serum osmolality were normal. His magnetic resonance imaging (MRI) showed an acute right parietal lobe infarction. Patients can experience hemiballismus with lesions other than the subthalamic nucleus in the basal ganglia. This is contrary to the classic belief that hemiballismus is associated with, and only with, lesions in the subthalamic nucleus. This manuscript describes a case of hemiballismus occurring in a patient secondary to a parietal lobe infarction.
人们普遍认为，偏身投掷症和舞蹈症提示基底节丘脑底核病变；然而，这并非绝对规律。我们报告一例63岁男性患者，其主诉言语含糊不清、左侧身体活动增多及头痛。他患有糖尿病、高血压，既往有中风病史，右侧身体遗留有虚弱症状。该患者突然出现左上肢和下肢不规则、大幅度、非自主运动增加，呈投掷样动作模式。他的血糖和血清渗透压正常。其磁共振成像（MRI）显示急性右顶叶梗死。除基底节丘脑底核病变外，患者在其他病变时也可出现偏身投掷症。这与经典观点相悖，即偏身投掷症仅与丘脑底核病变相关。本文描述了一例因顶叶梗死继发偏身投掷症的患者。
