目的：比较脑膜原发外周型原始神经外胚层肿瘤与血管瘤型脑膜瘤MRI征象差异。材料与方法应用FISHER确切概率法回顾性分析经手术病理证实的10例脑膜原发原始神经外胚层肿瘤与15例血管瘤型脑膜瘤的术前MRI影像学资料，比较两种脑膜肿瘤MRI征象差异。结果脑膜原发原始神经外胚层肿瘤与血管瘤型脑膜瘤相比，前者更多见MR平扫信号混杂、坏死囊变、强化不均匀、邻近骨质改变(P值均＜0.05)，后者更多见血管流空及瘤周中重度水肿(P值均＜0.05)，T2高信号、强化程度等高于血管、分叶状、瘤脑界面模糊、脑膜尾征5项影像征象差异无统计学意义(P均＞0.05)。结论脑膜原发原始神经外胚层肿瘤与血管瘤型脑膜瘤MRI征象存在差异，有助于二者鉴别诊断。

Objective: To compare difference of MRI signs between the meninges primary peripheral primitive neuroectodermal tumor and angiomatous type meningioma.Materials and Methods: Retrospectively analyzed preoperative MRI imaging data of 10 patients meningeal primary primitive neuroectodermal tumors and 15 cases of angiomatous type meningioma pathologically confirmed, comparing the differences of the MRI signs of the two meningeal tumor.Results:In the signs, some are more common in meningeal primary primitive neuroectodermal tumors, such as mixed signals in unenhanced MR, cystic necrosis, inhomogeneous enhancement adjacent bone changes (P<0.05), and some are more common in angiomatous type meningioma such as lfowing void effect and peritumoral edema (P<0.05), and others, such as high signal of T2WI, strengthen higher degree of vascular , lobulated , fuzzy brain tumor interface, signs of meningeal tail showed no signiifcant difference (P>0.05). Conclusions:There is difference in MRI signs between meningeal primary primitive neuroectodermal tumor meningioma tumors and angiomatous type meningioma , which is helpful in the differential diagnosis.
