目的探讨颈动脉海绵窦瘘的MRI特点,以提高对该病的认识及评估治疗的作用。方法回顾分析8例颈动脉海绵窦瘘的临床资料及影像学表现,所有病例均行MRI、MRA、CT及数字减影血管造影(DSA)检查证实,对比分析患者MRI及MRA影像征象。结果患侧眼球突出8例,海绵窦扩张8例,其中1例为双侧海绵窦扩大,眼上静脉扩张7例,岩上、岩下窦扩张1例,岩上窦扩张1例,眼肌增粗1例,脑挫伤3例。结论颈动脉海绵窦瘘的MRI及MRA具有一定特征性,结合临床对该病的诊断和治疗具有重要的作用。且有成像简单、方便、快捷、无创等优点,是首选的检查方法。
Objective To explore the MRI features of carotid cavernous fistula to improve the understanding of the disease and evaluate the effect of treatment. Methods The clinical data and imaging findings of 8 cases of carotid cavernous fistula were retrospectively analyzed. All cases were confirmed by MRI, MRA, CT and digital subtraction angiography (DSA). The MRI and MRA images were compared and analyzed. Results In the affected side, there were 8 cases of protrusion of the eyeball and 8 cases of cavernous sinus dilation. One case had bilateral cavernous sinus enlargement, 7 cases of dilated ophthalmic vein, 1 case of petrous apex, 1 case of inferior petrosal sinus dilation, 1 case of dural sinus anastomosis, Cases, brain contusion in 3 cases. Conclusion MRI and MRA of carotid-cavernous fistulas have certain characteristics. Combined with clinical diagnosis and treatment of the disease, it has an important role. And imaging is simple, convenient, fast, non-invasive, etc., is the preferred method of inspection.
