摘要

目的：探讨MRI征象在恶性脑膜瘤术前诊断中的价值。方法：回顾性分析23例恶性脑膜瘤的MRI征象，并随机抽取同期34例良性脑膜瘤作为对照。结果：分叶征、囊变坏死、瘤脑界面、瘤脑界面的边缘、T1WI信号、信号不均匀性、强化不均匀性、强化程度、脑膜尾征的有无及形态与脑膜瘤良、恶性相关。结论：恶性脑膜瘤的MRI表现具有一定的特征性，评价某些MRI征象对恶性脑膜瘤的术前定性诊断具有重要意义。

Abstract

Objective: To investigate the value of MRI features in preoperative diagnosis of malignant meningioma. Methods: MRI findings in 23 patients with malignant meningioma were analyzed retrospectively, and 34 cases of benign meningiomas in the same period were randomly selected as control. Results: Lobulation, cystic necrosis, tumor-brain interface, tumor-brain interface rim, signal intensity in T1WI, signal inhomogeneity, inhomogeneous contrast enhancement, the degree of contrast enhancement and dural tail sign are related to the gradings of meningioma. Conclusion: Malignant meningiomas do have characteristic MRI features, to evaluate some MRI features has important significance in qualitative diagnosing malignant meningioma before operation.
