It is exceedingly rare for dural arteriovenous fistulae (DAVFs) outside of the cavernous sinus to present with ophthalmological symptoms and signs. Hypoglossal canal DAVFs (HC-DAVFs) have only previously been reported as individual cases or small case series. Further, only an estimated 31% of HC-DAVFs present with ophthalmological findings. We report a noteworthy case of an HC-DAVF in a 74-year-old male who presented with proptosis, chemosis, and reduced visual acuity. He was treated endovascularly with liquid embolic filling. This report aims to highlight HC-DAVF as an important differential diagnosis for patients presenting with symptoms suggestive of arterialisation of the ophthalmic veins.
海绵窦外的硬脑膜动静脉瘘（DAVFs）出现眼科症状和体征极为罕见。舌下神经管硬脑膜动静脉瘘（HC-DAVFs）此前仅作为个别病例或小病例系列报道过。此外，据估计只有31%的HC-DAVFs出现眼科表现。我们报告了一例值得关注的HC-DAVF病例，患者为一名74岁男性，表现为眼球突出、球结膜水肿和视力下降。他接受了液体栓塞填充的血管内治疗。本报告旨在强调HC-DAVF作为出现提示眼静脉动脉化症状患者的重要鉴别诊断。
