目的：研究颅内血管外皮细胞瘤(HPC)与不同病理类型脑膜瘤的 MRI、CT 影像特征的差别。方法经手术病理证实的 HPC 8例及脑膜瘤51例，术前均经 MRI 平扫、CT 平扫及增强检查。对各组肿瘤的 MRI 及 CT 表现进行统计学分析，统计学方法采用卡方检验。结果与非典型脑膜瘤比较，瘤内出血(χ2=11.484)、流空血管(χ2=8.571)、颅骨破坏(χ2=5.529)等因素差异有统计学意义(P <0.05)；与恶性脑膜瘤比较，瘤内出血(χ2=11.484)、流空血管(χ2=11.429)等因素差异具有统计学意义(P <0.05)。结论HPC 与各种病理类型脑膜瘤的 MRI 及 CT 表现各有特点，通过各种征象对比分析，有助于提高两者术前诊断的准确度。

Objective To study the characteristic differences using CTs and MRIs between intracranial hemangiopericytomas (HPCs)and meningiomas of different pathological type.Methods 8 cases of HPC and 5 1 cases of meningioma approved by patholo-gy were selected.All cases underwent MRIs,CTs and enhancements before operation.The imaging characteristics of these tumors were analyzed with chi-square test.Results Compared with atypical meningioma,tumor bleeding(χ2 = 1 1.484),blood vessel flow void phenomenon(χ2 =8.571),skull damage(χ2 =5.529)showed remarkably significant statistical differences(P <0.05);compared with malignant meningioma,tumor bleeding(χ2 =1 1.484),blood vessel flow void phenomenon(χ2 = 1 1.429)showed remarkably significant statistical differences(P <0.05).Conclusion There are differences between HPC and meningiomas of different pathologi-cal type.It is helpful to improve the diagnosis level through comparative analysis of the MRI and CT findings.
