Hemiballism-Hemichorea: Coincidence of a Small Hematoma in the Subthalamic Nucleus Detected by CT of the Brain

半側跳躍舞蹈症:腦部斷層攝影同時顯示視丘下核局部出血

摘要


半側跳躍舞蹈症病人大都由於腦部血管疾病引起,大多數病人為腦部血管梗塞,僅少數為出血。我們提出一位39歲出血性中風病人之病歷,病人臨床症狀除了肢體半側輕癱外,其同側肢體同時出現半側跳躍舞蹈症之特徵。腦部電腦斷層檢查顯示對側視丘下核有局部出血。此不自主運動對haloperidol(劑量2.5/day)之治療反應甚佳,七天後症狀痊癒。本文除提出此病例外,並探討其病理學機轉。

並列摘要


Most patients with hemiballism-hemichorea had a vascular lesion in the subthalamic nucleus, usually due to infarction rather than hemorrhage. A 39 year old male who suddenly developed left hemiballism-hemichorea in addition to ipsilateral hemiparesis. The computed tomography (Cf) scan of the brain demonstrated a focal hemorrhage in the contralateral subthalamic nucleus. His involuntary .movement was treated with haloperidol and the symptom compeltely remitted 7 days later. In this report, we present our finding and discuss the possible pathophysiology of the hemiballism-hemichorea.
