摘要
目的 探讨脑膜瘤MRI征象与病理关系。方法 41例脑膜瘤的MBI特征与手术病理对照分析。结果 不同组织亚型脑膜瘤T1WI及T2WI信号强度均无显著差异(P>0.05)。41例中有完整包膜者25例,而7例包膜明显不完整者同时伴瘤脑界面不清;16例肿瘤血管丰富者瘤周水肿多较明显;24例显示硬膜”尾”征,其中18例有肿瘤细胞浸润。结论 脑膜瘤的MRI征象与病理亚型无明显相关性。
Objective To study the relationship between MRI manifestations and pathological findings in patients with men-ingioma. Method MRI features of 41 cases of meningiomas were compared with their pathological findings. Results There was no significant difference between the histological subtypes in the signal intensity of MRI. 25 in the 41 miningiomas, had their integral capsules. There were 7 cases whose capsules were incomplete and the brain-tumor interfaces were markedly obscured. Peri-tu-moral edema were found in 16 cases of tumors with rich blood supply. Dural 'tail sign was present in 24 cases of which, 18 showed infiltration of tumor cells. Conclusion The authors concluded that there is no correlative relationship between the MRI features and the histological subtypes of meningioma.
