眼眶海绵状血管瘤的MRI影像特征与意义

目的研究眼眶海绵状血管瘤在MRI影像特征与诊断价值。方法对46例眼眶海绵状血管瘤进行MRI平扫,其中44例进行了增强扫描。结果MRI可以反映肿瘤的特征,可以从多方位对肿瘤的影像表现进行诊断,明确肿瘤与眼眶及视神经的关系,及肿瘤的“渐进性强化”特性。结论MRI可以对眼眶海绵状血管瘤进行很好的定位及定性,为手术方式的选择提供可靠的影像依据。

MRI findings of orbital cavernous hemangioma

Objective To study MRI findings of orbital cavernous hemangioma. Methods Forty-six cases with orbital cavernous hemangioma underwent MRI plain scan, forty-four of which underwent enhanced scan. Results MRI may reflect the characteristics of tumors. We can make the all-directional diagnosis according to the findings of MRI to make clear the relationship between the tumors and the orbit and the optic nerve, and the characteristics of "progressive enhancement". Conclusion We can diagnose orbital cavernous hemangioma through their signs, which is helpful to localiza- tion of the tumor and choice of different operation methods.
