摘　　要：目的评价硬脊膜外海绵状血管瘤MRI特征表现。方法回顾性分析3例经手术病理证实的硬脊膜外海绵状血管瘤的MR表现及文献复习。结果3例硬脊膜外海绵状血管瘤中,1例位于腰段椎管,2例位于胸段椎管,3例均发生于脊髓背侧,两端尖细,长轴与脊椎纵轴一致,相应平面的脊髓均受压推移;3例均表现为T2WI高信号,Gd-DTPA增强扫描呈均匀一致的明显强化。结论MRI检查是诊断此病的最佳无创检查方法。Objective To analyze the MRI characteristics of cavernous angioma of the epidural space in spine. Methods MR imaging features of cavernous angioma of epidural space in 3 cases confirmed by surgery - pathology were analysed with literature review . Results Among the three cases, the tumors located in the lumbar spine in one and in the thoracic spine in 2. The tumors were all at posterior to the spinal cord and shuttle - shaped, the major axis was consistent with the spinal ordinate axis, the corresponding plane spinal cords were compressed and resulting in distortion and shift. The tumors were high signal intensity on T2WI,and obviously homogeneous enhanced after Gd - DTPA administration. Conclusion MRI examination is the best method to diagnose this kind of disease.
