摘要
目的 提高对恶性脑膜瘤的认识和诊断能力。方法 收集本院脑膜瘤的临床病理资料,进行回顾性总结及文献复习。结果 34例脑膜瘤中,仅3例为恶性脑膜瘤。3例中,临床术前诊断仅1例,另2例分别为胶质瘤和转移癌。结论 病理诊断脑膜瘤,一定要抓住其特征性细胞又结构,不典型病例诊断困难时,可借助于免疫组织化学技术,帮助鉴别诊断。恶性脑膜瘤关键的诊断依据是:肿瘤组织侵犯脑组织,肿瘤细胞有明显的异型,多量的核分裂及大片的肿瘤组织坏死。
Objective To improve the diagnosis of malignant meningoma. Methods The clinicopathologic data of meningoma were studied retrospectively. Results There were 3 cases of malignant meningoma in 34 cases of meningoma. 1 case had been confirmed before surgery. The other 2 cases were glioma and metastatic carcinoma respectively. Conclusions Characteristic cells and construction are very important to pathological diagnosis of meningoma. Immunohistochemical method is helpful to untypical cases. The tumor histiocyte invading brain, the obvious heterotype of tumor, much of karyokinesis and a lot of necrosis are the chief basis of malignant meningoma.
