【摘要】：目的:分析磁共振对比增强血管成像(CE-MRA)联合常规磁共振成像(c MRI)对脊髓血管母细胞瘤显示的影像学特征,旨在提高对脊髓血管母细胞瘤的诊断。方法:搜集经术后病理证实17例脊髓血管母细胞瘤c MRI和CE-MRA影像学资料,回顾性分析脊髓血管母细胞瘤影像特征。结果:17例脊髓血管母细胞瘤患者中病灶分布于颈髓5例,于胸髓12例。呈实质性结节型6例,囊肿伴空洞型11例。病灶直径10mm 11例,病灶直径10 mm 6例。对于病灶直径较大的患者,c MRI可以发现其周围迂曲的流空血管信号。CE-MRA可以清晰显示病灶实质、供血动脉及粗大的引流静脉。结论:脊髓血管母细胞瘤的CE-MRA及c MRI具有特征表现,CE-MRA可以显示肿瘤的供血动脉和引流静脉,是确诊脊髓血管母细胞瘤的有益补充。
[Abstract]:Objective: to analyze the imaging features of spinal hemangioblastoma by contrast-enhanced magnetic resonance angiography (CE-MRA) combined with conventional magnetic resonance imaging (MRI) in order to improve the diagnosis of spinal cord hemangioblastoma.Methods: the imaging data of c MRI and CE-MRA in 17 cases of spinal cord hemangioblastoma confirmed by postoperative pathology were collected and the imaging features of spinal cord hemangioblastoma were analyzed retrospectively.Results in 17 cases of hemangioblastoma of spinal cord, 5 cases were located in the cervical spinal cord and 12 cases in the thoracic spinal cord.There were 6 cases of parenchymal nodular type, 11 cases of cyst with cavity type.The diameter of lesions was 10mm in 11 cases and 10 mm in 6 cases.CE-MRA could clearly display the lesion parenchyma, the feeding artery and the coarse drainage vein in patients with larger lesion diameter.Conclusion: CE-MRA and c MRI of spinal cord hemangioblastoma have characteristic features. CE-MRA can show the supplying artery and drainage vein of spinal cord hemangioblastoma, which is a useful supplement for the diagnosis of spinal cord hemangioblastoma.
