摘要
目的评估MRI在脊柱血管瘤临床诊断中的应用价值。方法收集2007～2012年诊断的20例VH患者资料,利用磁共振成像设备对患者进行常规TSE序列T1WI、T2WI及T2WI压脂的横断面、矢状面扫描。其中14例行矢状位、轴位T1WI压脂增强扫描。结果病程3周～36个月,平均(8.7±2.6)个月。所有患者均有临床症状,6例表现为局部疼痛,余14例出现局部疼痛伴下肢乏力,呈进行性加重。共检出胸椎受累6例(30%)、腰椎9例(45%)、颈椎5例(25%),其中多发性4例(20%),病灶达27个。17例可见椎旁软组织肿块,17例可见椎管内硬膜外软组织肿块,神经根受压12例,脊髓受压17例。病灶呈T1WI低信号/T2WI等信号5例,T1WI低信号/T2WI高信号7例,T1WI等信号/T2WI高信号5例,T1WI低信号/T2WI低信号2例,T1WI高低混杂信号/T2WI高低混杂信号1例。14例患者做MRI增强后,9例表现为明显均匀强化,2例明显不均匀强化,2例轻度均匀强化,1例轻度不均匀强化。结论 MRI在推测VH组织学类型、评价其活动性或潜在的侵袭性方面具有良好的临床应用价值。
Objective To investigate the value of magnetic resonance imaging（MRI） in the use of diagnosis of vertebral hemangiomas. Methods Twenty patients who were suffered from VH during 2007 to 2012 were performed by MRI. Results Of the 20 cases, all of them had clinical symptoms,6 had local pain,other 14 had local pain with lower limb weakness increased progressively.Lesions included 5 in the cervical spine（25%）, 6 in the thoracic（30%） and 9 in the lumbar（45%）.We can find that visible paravertebral soft tissue mass in 17 cases,spinal epidural soft tissue mass in 17 cases, nerve root compression in 12 cases,spinal cord compression in 17 cases.Five lesions appeared low signal on T1WI and equal signal on T2WI,7 cases with low T1WI and high T2WI, 5 cases with equal T1WI and high T2WI,2 cases with low T1WI and low T2WI, 1 cases with mixed T1WI and mixed T2WI. Conclusion It is a good clinical value of MRI in the speculation of histological type of VH and evaluation of VH aggressiveness.
