目的探讨CTA和MRI在颈髓血管网织细胞瘤中的应用价值。方法回顾性分析6例经病理证实的颈髓单发血管网织细胞瘤的术前CTA和MRI平扫及增强扫描图像,观察病变引起的继发性脊髓变化、血管流空现象及肿瘤血管显示情况,并与术中所见相比较。结果 6例病变在CTA图像上均表现为明显强化的实性瘤体与供血动脉相连,MRI检查可显示肿瘤造成的颈髓中央管扩张、脊髓实质的水肿和血管流空影,术中可见瘤体的供血动脉和引流静脉。结论颈髓血管网织细胞瘤的CTA和MRI检查能分别显示不同的影像学征象,两者的综合运用能更好地显示该病的影像学特点。

英文摘要：

Objective To explore the value of CT angiography（CTA）and MRI in the cervical spinal hemangioblastoma.Methods We retrospectively analyzed the pre-operative CTA and MRI findings of 6patients（3males,3females,age range,11-55years old,mean age,27 years old）with cervical spinal hemangioblastoma,which were pathologically diagnosed.The radiological analysis was focused on the secondary spinal cord changes,flow-void signs,and tumoral vessels and compared with operational findings.Results On CTA,all of the solid parts of tumors showed as vivid enhancement and connected with feeding arteries.On MRI,edematous spinal cord and dilated spinal canal were demonstrated due to the presence of tumor itself.Flow-void signs were also revealed.During operation,macroscopically,the feeding arteries and draining veins of the tumors were found.Conclusion CTA and MRI can reveal different signs of spinal cord hemangioblastomas.The combined usage of the two methods is helpful for the disease.
