摘　　要：目的:分析颅内血管外皮细胞瘤(HPC)的MRI表现,提高对该病的诊断水平。方法:回顾性分析9例经手术病理证实的HPC病例的MRI征象,并将其与手术相对照。9例病灶均行MRI平扫及增强扫描。结果:9例HPC均呈分叶状肿块,信号不均匀,其中5例可见囊变、坏死,7例可见血管流空信号,增强扫描肿瘤实体部分强化明显。所有病例均行手术治疗及放射治疗,7例行肿块全切除,2例行肿块次全切除。5例患者随访3～36个月,其中1例局部复发,1例发生远处转移。结论:颅内HPC的MRI表现具有一定的特征性,有助于术前准确诊断。手术将肿瘤全切除是HPC的最佳治疗方法,术后辅以放射治疗可改善预后。Objective：To study the MRI features of intracranial hemangiopericytoma （HPC） in order to obtain a fur- ther understanding of this disease. Methods： 9 patients with surgery and pathology proved HPC were retrospectively ana- lyzed and correlated with surgical findings. All 9 cases underwent plain and contrast-enhanced MR imaging. Results：All 9 HPCs tended to be lobulated in shape,with heterogeneous signal intensities due to cystic change and necrosis,vascular flow void signal could be seen in 7 cases. The solid component of tumor showed marked enhancement. All the patients were trea ted with surgery and radiation. Total resection was performed in 7 patients and subtotal resection in 2 patients. 5 patients were followed up for 3 to 36 months after surgery,1 case had local recurrence,and 1 case had distant metastasis. Conclusion： Certain MRI characteristics could be assessed in intracranial hemangiopericytoma, which are helpful for preoperative diagno- sis. Total resection of tumor is the optimal treatment for HPC, the outcome could be improved by post-surgery radiation therapy.
