颅内血管周细胞瘤与非典型脑膜瘤的磁共振征象特征差异分析

Analysis on the Difference of MRI Features Between Intracranial Hemangiopericytoma and Atypical Meningioma

目的探讨颅内血管周细胞瘤与非典型脑膜瘤的磁共振征象特征差异。方法收集105例颅内血管周细胞瘤与104例非典型脑膜瘤患者,均行MRI平扫及增强扫描,对比两组患者的磁共振征象特征。结果两组患者的T1WI等信号、囊变坏死、瘤周水肿程度及硬脑膜宽基底相连等因素比较,差异有统计学意义(P <0.05)。结论磁共振可鉴别颅内血管周细胞瘤与非典型脑膜瘤,分析磁共振征象特征可提高鉴别准确性。

Objective To investigate the differences in the MRI features between intracranial hemangiopericytoma and atypical meningioma.Methods 105patients with intfacranial hemangiopericytoma and 104patients with atypical meningioma were collected,and all cases received MRI plain scan and enhanced scan.The differences of MRI features were compared between the two groups.Results The DWI equal signal,necrosis of cysts,degree of edema around the tumor and necrotic necklaces of the dural width basement were statistically different between intracranial hemangioma and atypical meningioma (P <0.05).Conclusions MRI can differentiate intracranial hemangiopericytoma from atypical meningioma,and analysis of MRI features can improve the accuracy of differentiation.
