Sigmoid sinus diverticulum, a rare dural sinus anomaly, is regarded as one of the very rare causes of pulsatile tinnitus, and there have been only a few reports on their surgical or endovascular management. We describe a 31-year-old woman presenting with a three-year pulsatile tinnitus in her right ear. After finding the small bony defect in her right temporal bone on CT which was filled with contrast after enhancement, we confirmed the presence of sigmoid sinus diverticulum with the cerebral angiogram and embolized it with two detachable coils in awake status. Right after filling the two coils into the sac, thanks to her alert consciousness, she was able to refer the disappearance of her tinnitus. The operation was finished only with the detachment of the coils.
乙状窦憩室是一种罕见的硬脑膜窦异常，被认为是搏动性耳鸣极为罕见的病因之一，关于其手术或血管内治疗的报道仅有少数几例。我们描述了一名31岁女性，她右耳出现搏动性耳鸣三年。在CT上发现其右侧颞骨有小的骨质缺损，增强后有造影剂充盈，随后通过脑血管造影证实了乙状窦憩室的存在，并在清醒状态下用两个可脱卸弹簧圈对其进行了栓塞。在将两个弹簧圈填入囊袋后，由于她意识清醒，她能够诉说耳鸣消失了。仅通过弹簧圈的脱卸手术就完成了。
