脊椎血管瘤的影像特征分析

Analysis of imaging of vertebral hemangiomas

目的分析脊椎血管瘤的影像学表现,评价不同影像手段对于该病的诊断价值。方法回顾性分析本院手术病理证实的12例脊椎血管瘤的X线片、CT和MRI影像征象。结果 12例患者共发现14个脊椎血管瘤病灶,其中10个椎体外形保持正常,2个椎体及附件轻度膨胀,2个椎体病理性压缩骨折改变。X线表现为纵行"栅栏样"特征影像,CT可见网眼状影像中夹杂着低密度脂肪;MRI T1WI夹杂高低信号,T2WI显示出高信号,冠状位重建可见"栅栏样"征象。结论脊椎血管瘤具有的特征性影像学表现,CT、MRI在显示小病灶及病灶范围方面优于X线片。

Objective To analyze the imaging features of vertebral hemangioma, evaluate the diagnostic value of different imaging methods for the disease. Methods A retrospective analysis of hospital pathologically confirmed 12 cases of vertebral hemangioma X-ray, CT and MRI. Results Twelve cases were found in 14 patients with verte- bral bemangioma lesions, including 10 vertebral body shape to maintain a normal, 2 vertebrae and accessories mild swelling, 2 pathologic vertebral compression fractures changed. X-ray showed a vertical line ＂fence-like＂ features images, CT visible mesh-like images mixed with low density fat; MRI TIWI mixed high and low signal, T2WI showed high signal, coronal reconstruction invisible ＂fence-like＂ signs. Conclusion Characteristic imaging findings of spinal hemangioma has, CT, MRI is superior to X-ray shows a small lesions and lesions in scope.
