腦幼裂頭絛蟲病是稀有的顱內寄生的感染症。其真實的發生率可能被低估。一名64歲男性以陣發性癲癇和左下肢無力為表現。顱內磁共振造影確認大腦的中央前回有病兆的存在。隨後的立體定位技術病理活檢顯示一只幼裂頭絛蟲的存在。雖然沒有切除整個病兆，我們成功的治療這位病患。因此我們建議處理的要點是透過去除寄生蟲蟲體而並非切除整個病兆。這種技術對病兆在顱內深部和功能區相當有用。
Cerebral sparganosis is an extremely rare intracranial parasitic infectious disease and its true incidence might be underestimated. A 64-year-old man presented a one-year history of episodic general tonic-clonic seizure and progressive left leg weakness. MRI of the brain confirmed the presence of a lesion of the right precentral gyrus. Subsequent stereotactic biopsy revealed plerocercoid larva or sparganum. We were able to treat this patient successfully using this stereotactic technique without exising the whole mass. So we suggested the key is to remove the parasite not excise the whole granuloma mass. This technique will be especially effective especially when the lesion is deep-seated or located in a sensitive cortical area.
