[Objective]To explore the clinical diagnosis and treatment of ophthalmoplegia caused by cavernous sinus dural arteriovenous fistulas (CDAVF) among type 2 diabetes mellitus. [ Methods ]Clinical data of one case of type 2 diabetes mellitus with ophthalmoplegia caused by CDAVF were analyzed retrospectively. [Results] Cere-brovascular digital subtraction angiography(DSA) showed that the patient was left dural arteriovenous fistulas of cavernous sinus. The symptoms of blephroptosis and eye movement of the patient were gradually improved after endovascular embolization of arteriovenous fistula was successfully performed. [Conclusion] The etiology of ophthalmoplegia is complex. Diabetic neuropathy is the major cause of type 2 diabetes mellitus with accidental cranial nerve injury. However, other factors such as intracranial spaceoccupying lesion and CDAVF should be considered. If necessary, imaging examination should be performed to confirm the cause of the disease.%[目的]结合文献复习,提出海绵窦区硬脑膜动静脉瘘致2型糖尿病患者眼肌麻痹的临床诊断和治疗策略.[方法]回顾分析本院1例由于海绵窦区硬脑膜动静脉瘘致眼肌麻痹的2型糖尿病患者的临床资料.[结果]脑血管数字减影造影(DSA)显示"左侧海绵窦区硬脑膜动静脉瘘",行"颅内动静脉瘘栓塞术"后患者上睑下垂症状及眼球运动逐渐改善.[结论]眼肌麻痹的病因复杂.对于糖尿病患者突发的颅神经受损,除了考虑糖尿病神经系统并发症外,还需排除其他颅内占位性病变及海绵窦区硬脑膜动静脉瘘可能,必要时可行影像学检查以明确病因.
