Cystic Intracranial Meningioma
顱內囊腫性腦膜瘤
摘要
高雄醫學院神經外科從1983年4月到1991年4月，收集了100位顱內腦膜瘤的病例，其中發現9位有囊腫的變化，佔所有腦膜瘤的9%，病人年齡大致分佈於40歲到75歲之間，有5位男性，4位女性，其中3位病例的囊腫位於中心，6位囊腫位於周圍。從組織學來看，七例為腦膜皮型(meningothelimatous type), 一例為砂樣型(psammomatous type), 另一例為血管胚細胞型(angioblastic type). 本報告之腫瘤均大於2公分。術前從CT上來看屬於Nauta’s type II者很難與壞死性神經膠瘤或轉移性瘤做鑑別診斷，此一型式術前是最難做鑑別診斷的一種。顯微手術剛摘除是預防其再發的唯一可能途徑。

Between April 1983 and April 1991, we studied nine cases of intracnanial meningioma with cystic change out of 100 intracranial meningioma patients. The incidence was 9%. The patient’s ages ranged from 40 years to 75 years old. There were five men and four women, of them, three had intratumoral cysts, and six had peritumoral cysts. Histologically, 7 cases were diagnosed as meningothelimatous type, one as psammomatous and the other one as angioblastic type. All the tumors with cystic change in this series were greater than two centimeters in diameter. Because the morphology was indistinct, Nauta’s type II cystic meningioma was easily misdiagnosed as glioma or metastatic tumors preoperatively. Microsurgery is the best way for complete removal of the cyst wall to prevent recurrence.
