发布时间：2018-11-09 11:36
【摘要】：目的 :探讨中枢神经系统血管外皮细胞瘤(hemangiopericytoma,HPC)的MRI特征表现以及临床治疗方法 。方法:收集本院经手术病理确诊的16例中枢神经系统血管外皮细胞瘤患者资料,回顾性分析其MRI表现、病理特征、临床治疗及预后。结果:16例肿瘤均位于颅内脑外,MRI显示肿瘤大多呈分叶状,T_1呈等或稍低信号,T_2呈稍高信号,肿块内可见囊变坏死及迂曲血管影;肿瘤血供丰富,增强扫描后明显强化,多数与静脉窦关系密切,“脑膜尾征”少见。所有病例均行手术治疗,6例患者术后行放射治疗。14例患者随访3~140个月,6例局部复发,其中1例同时发生远处转移。结论:中枢神经系统血管外皮细胞瘤的MRI表现有一定特征性,有助于提高其术前诊断的准确性。手术切除是HPC的最佳治疗方法 ,术后辅以放射治疗可改善预后。
[Abstract]:Objective: to investigate the MRI features and clinical treatment of hemangiopericytoma (hemangiopericytoma,HPC) of the central nervous system. Methods: the data of 16 patients with angiopericytoma of the central nervous system confirmed by operation and pathology were collected and their MRI features, pathological features, clinical treatment and prognosis were analyzed retrospectively. Results: all the 16 tumors were located outside the brain. MRI showed that most of the tumors were lobulated, the signal intensity of T _ (1) was equal or slightly low, the signal of T _ 2 was slightly high, and the cystic necrosis and tortuous vascular shadow could be seen in the tumor. The blood supply of the tumor was abundant and enhanced obviously after enhanced scan, most of them were closely related to the venous sinus, and meningeal caudal sign was rare. All cases were treated by operation, 6 cases were treated by radiotherapy, 14 cases were followed up for 3 ~ 140 months, 6 cases had local recurrence, and 1 case had distant metastasis. Conclusion: the MRI findings of central nervous system hemangiopericytoma are characteristic and helpful to improve the accuracy of preoperative diagnosis. Surgical resection is the best treatment for HPC. Postoperative radiotherapy can improve the prognosis.
