目的：探讨视神经血管性卡压的MRI表现。方法回顾性分析18例视神经颅内段受邻近动脉卡压的MRI表现特点和临床资料。结果视神经受邻近动脉卡压情况包括：颈内动脉和大脑前动脉卡压同侧视神经交叉前段占多数，共15例（15/18），前交通动脉与大脑前动脉卡压、颈内动脉与眼动脉卡压及Heubner回返动脉各1例。MRI表现为：邻近血管与视神经接触，两者之间脑脊液间隙消失；视神经可见深浅不一压迹；极少病例出现视神经信号异常。结论 MRI对视神经血管性卡压的观察具有其他检查不具备的独特优势。只要我们平时在工作中给予足够重视，熟悉鞍区视神经及周围血管解剖结构，根据MRI直接或间接表现得出正确诊断并不难。

Objective To explore the MRI value in optic nerve vascular compression. Methods The MRI performance and clinical data of 18 cases which optic nerve intracranial segment compressed by adjacent arteries were analyzed retrospectively. Results Optic nerve compressed by adjacent arteries include: the compressed of the anterior cerebral artery and internal carotid artery were common with 15 cases (15/18), the compressed of arteriae communicans artery and anterior cerebral artery 1 case, the compressed of internal carotid artery and ophthalmic artery 1 case and Heubner artery 1 case. The optic nerve was contacted with nearby blood vessels on MRI imaging, and the cerebrospinal fluid between disappeared, the optic nerve impression could be seen. The abnormal optic signal could be seen in very few case. Conclusion MRI had unique advantages in observing the compress of optic nerve. As long as we pay attention to it during the work and be familiar with the anatomy of sellar region, we could make the correct diagnosis.
