摘要:
目的:探讨微囊型脑膜瘤与脑膜尤文肉瘤/外周原始神经外胚层肿瘤(pPNET)的MRI征象。方法:回顾性分析经病理证实的14例微囊型脑膜瘤和10例脑膜尤文肉瘤/pPNET患者的临床、影像学及病理资料,结合相关文献分析其MRI差异。结果:微囊型脑膜和脑膜尤文肉瘤/pPNET患者MRI特征在肿瘤形态、T2信号、强化特征、骨侵犯及远处转移方面有统计学意义(P<0.05);而在T1信号、硬膜尾征和瘤周水肿无统计学意义(P>0.05)。结论:微囊型脑膜瘤和脑膜尤文肉瘤/pPNET影像表现有差异,术前精准鉴别诊断有助于改善临床决策和预测预后。
Abstract:
Abstract: Objective To explore the magnetic resonance imaging (MRI) features of microcystic meningioma and meningeal Ewing sarcoma/peripheral primitive neuroectodermal tumor (pPNET). Methods The clinical, imaging and pathological data of 14 cases of pathologically confirmed microcystic meningioma and 10 cases of pathologically confirmed meningeal Ewing sarcoma/pPNET were retrospectively analyzed, and the differences in MRI features were analyzed, referring to relevant literatures. Results The MRI features such as tumor morphology, T2 signal, enhanced features, bone invasion and distant metastasis of microcystic meningiomas were different from those of meningeal Ewing sarcoma/pPNET, with statistical significances (P<0.05), while no statistical difference was found in T1 signal, dural tail sign and peritumoral edema (P>0.05). Conclusion There are differences in the imaging features of microcystic meningioma and meningeal Ewing sarcoma/pPNET. Preoperative accurate differential diagnosis contributes to improving clinical decision-making and prognosis prediction.
