摘　　要：目的:分析颅内血管外皮瘤的MRI影像学表现,为临床诊治提供有效依据。方法:回顾我院近3年经手术确诊的4例颅内血管外皮瘤的MRI影像表现,并结合相关文献讨论。结果:4例患者的颅脑MRI检查均能清楚显示颅内脑外的占位病变,T1WI呈等低的混杂信号,T2WI呈等高低混杂信号,其内见管状的流空信号,肿块边缘不规则,外缘与硬脑膜以窄基底相连,2例肿块见少许的瘤周水肿;增强扫描见肿块明显强化。结论:颅内血管外皮瘤是富血管的颅内脑外的占位病变,具有特征性的MRI影像表现,MRI检查能为临床制定手术治疗方案提供有效的诊断依据。Objective To provide a reliable image basis for clinical diagnosis and treatment for intracranial hemangiopericytomas( HPC) through analyzing the MRI findings. Methods Four patients with HPC were confirmed by surgical pathology in our hospital over the last three years,their MRI findings and the related literatures were analyzed retrospectively. Results The brain MRI of 4 cases with HPC clearly showed the intracranial occupying lesions,isointensity or hypointensity mixedsignal on T1WI,hypointensity or hyperintensity mixed-signal on T2WI,and with tubular flow void signal. The margin of tumors was irregular,the outer edge and dura mater were connected by a narrow base. Slightly peritumoral edema were found in 2 cases. The solid component of tumors showed enhancement obviously. Conclusion HPC is an intracranial occupying lesions with abundant vascularization,its MRI performance is characteristic,which can provide effective evidence for imaging diagnosis and surgical treatment.
