Parkinsonism Secondary to Chronic Subdural Hematoma Showing in the TRODAT-1 Scanning

慢性硬腦膜下腔血腫引發次發性帕金森氏症在多巴胺轉運體掃描下的影像

摘要


慢性硬腦膜下血腫是指腦外傷後3 周以上出現臨床症狀者,主因橋靜脈撕裂,血液於硬腦膜下腔積聚。雖然相關案例不多,但慢性硬腦膜下腔血腫也有機會因為壓迫中腦而導致次發性的帕金森氏症。我們在此提出一位83 男性因懷疑帕金森氏病而接受多巴胺轉運體掃描(Tc-99m TRODAT-1 SPECT imaging),進而偶然發現慢性硬腦膜下腔出血。影像中可見右側基底核處訊號相對左側較低,且於左側前方有明顯低訊號的新月形腫塊。外科手術治療後,病人部分症狀緩解。臨床上,在鑑別診斷帕金森氏症時,須謹慎評估可能病因,次發性帕金森氏症的病人經過適當的治療處置,有機會獲得良好的預後。

Chronic subdural haematoma (CSDH) is an encapsulated collection of old blood, mostly or totally liquefied and located between the dura mater and the arachnoid mater. A subdural hematoma can cause parkinsonian symptom as a result of compression on the mid-brain, but the actual cases are rarely reported. We herein reported a case of CSDH discovered incidentally by Tc-99m TRODAT-1 SPECT during a work-up for Parkinson’s disease. Surgical evacuation of the hematoma of this patient resulted in a partial recovery. This report recapped the multifaceted possibility of parkinsonism which necessitated a thorough and detailed assessment.
