摘要
目的对比分析WHOⅡ级脑膜瘤和WHOⅠ级脑膜瘤的影像征象,更好地对两者进行鉴别诊断。方法收集本院经手术治疗的137例WHOⅠ级脑膜瘤与32例WHOⅡ级脑膜瘤的影像、病理资料,对两种不同级别脑膜瘤的病理类型及影像征象(形态、肿瘤有无囊变、平扫信号均匀性、强化均匀性、瘤周水肿程度、瘤脑界面、脑膜尾征、邻近颅骨改变等)进行回顾性分析。结果 169例脑膜瘤中WHOⅠ级脑膜瘤137例,WHOⅡ级脑膜瘤32例,本组WHOⅠI级脑膜瘤与WHOⅠ级脑膜瘤相比,分叶状、肿瘤囊变、平扫信号不均、强化不均匀程度、瘤周水肿程度、瘤脑界面模糊6项MR征象差异有统计学意义(P<0.05);邻近颅骨改变、脑膜尾征差异无统计学意义(P>0.05)。结论 WHOⅡ级脑膜瘤与WHOⅠ级脑膜瘤在肿瘤分叶、囊变、平扫信号均匀性、瘤周水肿、瘤脑界面、强化均匀程度方面存在差异,有助于鉴别这两种级别脑膜瘤。
Objective To analyze imaging features of WHO grade 1, II meningiomas for a better differential diagnosis. Methods The pathological and imag-mg data of 137 cases of grade I meningionla and 32 cases of grade II meningioma which were treatable by surgery were studied in terms of pathological types and MRI features such as Iobulated sign, necrosis and cystic change, homogenous signal intensity, homogenous enhancement, peritumoral edema, brain tumor interfitce, dural tail sign and adjacent bone change.Results In 169 intracranialmeningiomas, there are 137 grade I meningiomas and 32WHO gradeII meningiomas,Differences in lobulated sign, necrosis and cystic change, heterogeneous enhancement and heterogeneous signal intensity, peritumoral edema, brain tumor interface, between WHO grade 1 meningioma and WHO grade II meningioma were statistically sigmificant（P〈0.05）, dural tail sign and adjacent bone change were not statistically significant（P〉0.05）.Conclusion The MRI features such as lobulated sign, necrosis and cystic change, peritnmoral edema, brain tumor interface, homogenous signal intensity and homogenous enhancement are helpful in differential diagnosis of WHO grade I meningioma and WHO grade II meningioma.
