| 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。 |
| 英文摘要: |
| 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 le-
sions 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 T2 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 spe-
cific and sensitive in the diagnosis of spinal cavernous angiomas. |
