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, M RI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。
目的:探討CTA和MRI在頸髓血管網織細胞瘤中的應用價值。方法迴顧性分析6例經病理證實的頸髓單髮血管網織細胞瘤的術前CTA和MRI平掃及增彊掃描圖像,觀察病變引起的繼髮性脊髓變化、血管流空現象及腫瘤血管顯示情況,併與術中所見相比較。結果6例病變在CTA圖像上均錶現為明顯彊化的實性瘤體與供血動脈相連, M RI檢查可顯示腫瘤造成的頸髓中央管擴張、脊髓實質的水腫和血管流空影,術中可見瘤體的供血動脈和引流靜脈。結論頸髓血管網織細胞瘤的CTA和MRI檢查能分彆顯示不同的影像學徵象,兩者的綜閤運用能更好地顯示該病的影像學特點。

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 6 patients (3 males ,3 females ,age range ,11~55 years old ,mean age ,27 years old) with cervical spinal hemangioblastoma ,which were pathologically diag-nosed .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 hemangio-blastomas .The combined usage of the two methods is helpful for the disease .
