在脑肿瘤中，脑膜瘤发病率仅次于胶质瘤。脑膜瘤多为实质性，发生囊性变着较少，据文献报告在4％～10％之间。我们复习了1989～1995年期间收治的脑膜瘤病例63例，其中4例为囊性脑膜瘤，占6．35％，均误诊为胶质瘤或转移瘤，现分析报告如下。1临床资料见附表2讨论2．1囊性脑膜瘤 In brain tumors, the incidence of meningiomas is second only to glioma. Meningiomas are mostly substantive cystic changes occur less, according to the literature reported between 4% to 10%. We reviewed 63 cases of meningiomas admitted from 1989 to 1995, of which 4 cases were cystic meningiomas, accounting for 6.35%, were misdiagnosed as gliomas or metastases, the analysis report is as follows. 1 clinical data, see Schedule 2 Discussion 2.1 cystic meningioma
