Radiologic studies of 57 solitary vertebral hemangiomas (VHs) were reviewed to find radiographic and computed tomographic (CT) criteria by which to distinguish asymptomatic lesions from those compressing the spinal cord. Six features were seen significantly more often in those compressing the cord: location between T-3 and T-9, involvement of the entire vertebral body, extension to the neural arch, an expanded cortex with indistinct margins, an irregular honeycomb pattern, and soft-tissue mass. Contrast material-enhanced CT scans and selective spinal angiograms demonstrated extension into the spinal canal. In patients with a VH and back pain of uncertain origin, the presence of three or more of these signs may indicate a potentially symptomatic VH. In such patients, spinal angiography and, in some cases, embolization, are indicated.
回顾了57例孤立性椎体血管瘤（VH）的放射学研究，以寻找用于区分无症状病变与压迫脊髓病变的X线和计算机断层扫描（CT）标准。在压迫脊髓的病变中，六种特征更为常见：位于T-3至T-9之间、累及整个椎体、延伸至神经弓、皮质扩张且边缘不清、不规则蜂窝状模式以及软组织肿块。对比增强CT扫描和选择性脊髓血管造影显示病变延伸至椎管。对于患有VH且背痛原因不明的患者，出现三种或更多这些征象可能提示潜在有症状的VH。在此类患者中，需进行脊髓血管造影，在某些情况下还需进行栓塞治疗。
