摘要目的探讨颅内血管外皮细胞瘤(HPC)与脑膜瘤的MRI特征，提高其临床诊断准确率。方法回顾性分析经手术病理证实的16例颅内HPC和95例脑膜瘤患者的MRI资料，MRI征象分析包括肿瘤边缘及形态、肿瘤内血管流空信号、肿瘤内囊变坏死、有无硬膜尾征、肿瘤增强的程度和强化方式。结果颅内HPC最大径为(5.40±1.72)cm，脑膜瘤最大径(4.43±1.35)cm，差异有统计学意义(t=2.551，P<0.05)。MRI在显示颅内HPC和脑膜瘤肿瘤边缘、肿瘤内血管流空信号、肿瘤内囊变坏死、强化方式、硬膜尾征等特征上的差异均有统计学意义(χ²=16.883、24.680、16.580、11.296、11.530，P值均＜0.05);两者在增强程度上差异无统计学意义(χ²=0.178， P＞0.05)。结论 MRI对肿瘤边缘及形态、肿瘤内血管流空信号、肿瘤内囊变坏死、强化方式、硬膜尾征等具有特征表现，对颅内HPC和脑膜瘤的鉴别诊断具有重要价值。

Abstract：Objective To analyze MRI features of intracranial hemangiopericytomas(HPC) and meningioma so as to improve their diagnostic accuracy.Methods MRI findings in 16 cases with HPC and 95 cases with meningioma confirmed by surgical and pathology were retrospectively analyzed. MRI signs included tumor maximum diameter, margin, signal voids of vessel in tumor, cystic degeneration or necrosis in tumor, "dural tail sign", enhancement pattern and degree.Results The maximum diameters of HPC and meningiomas were (5.40±1.72)cm and (4.43±1.35)cm, respectively, and the difference was statistically significant (t=2.551, P＜0.05). There were statistically significant differences in tumor margin, signal voids of vessel in tumor, cystic degeneration or necrosis in tumor, enhancement pattern and degree, and "dural tail sign" (χ²=16.883, 24.680, 16.580, 11.296, 11.530, P＜0.05), while no statistically significant difference in the enhancement degree.Conclusions Imaging findings of HPC had larger maximum diameter, more cross-leaf growth tendency, more signal voids of vessel, more necrosis, more cystic changes giving rise to heterogeneous signals, rarer frequency of the "dural tail sign" than meningiomas. These features may help differentiate them.
