硬脑膜动静脉瘘（davf）是一种罕见但重要的发生在颅底的瘘，在血管造影上可能与边缘窦davf混淆。MR血管造影源图像可以记录该类型瘘的骨内范围及其与舌下管的关系，具有重要的临床意义。我们报告了3例位于前髁静脉和舌下管内的davf的血管造影、CT和MR血管造影的影像特征，并通过MR血管造影的源图像证实了这些特征。经静脉线圈栓塞在三个病例中有两个是治愈的，当静脉通路可用时，似乎是治疗的选择。
Dural arteriovenous fistulas (DAVFs) of the anterior condylar vein are an uncommon but important subset of fistulas occurring at the skull base that can be confused with DAVFs of the marginal sinus on angiography. MR angiography source images can document the intraosseous extent and the relationship to the hypoglossal canal of this type of fistula, which can have significant clinical implications. We present the imaging features of angiography, CT, and MR angiography of three cases of DAVFs localized to the anterior condylar vein and within the hypoglossal canal, which were confirmed by source images from MR angiography. Transvenous coil embolization was curative in two of three cases and would seem to be the treatment of choice when venous access is available.
