脊髓海绵状血管瘤MRI 诊断

目的　评价脊髓海绵状血管瘤的MRI表现。方法　对 3例临床确诊的脊髓海绵状血管瘤病人做了MRI扫描 Gd DTPA增强扫描。结果　 3例脊髓海绵状血管瘤中 2例病灶位于胸段 ,1例位于下颈段脊髓 ,均为单发 ,脊髓粗细正常或稍增粗。MRI特征性表现为瘤巢呈爆米花状或桑葚状混合信号团块 ,周围可见短T2 低信号环。Gd DTPA增强扫描 2例未见明显强化 ,1例呈中等度增强。瘤巢较小 ,一般不超过脊髓横径。结论　MRI诊断脊髓海绵状血管瘤特异性高、敏感度强 ,具有特征性表现

The Diagnosis of Magnetic Resonance Imaging (MRI) for Spinal Cavernous Angiomas

Objectives To assess the presentation of MRI for spinal cavernous angiomas. Methods Three patients with spinal cavernous angiomawere examined by plain scanning and Gd|DTPA strengthened scanning of MRI. Results The lesions of two cases were located in throax segment of the spinal cord, and one in the low cervical segment.There was only one hemangioma in every patient.The shape of the spinal cord was ordinary or a little bit thicker.The MRI characteristic of the hemangioma was just like popcorn or mulberry,and the signal was a jumbled gobbet.And low short T 2 signal could be seen around the lesion.There was no obvious strengthened sign when using Gd|DTPA strengthened scanning except one was moderately strengthened.The diameter of hemangioma was smaller than that of the spinal cord. Conclusion MRI was specific and sensitive in the diagnosis of spinal cavernous angiomas. [
