MR imaging showed swelling and diffuse signal changes in the spinal cord in two patients with progressive myelopathy. MR angiography revealed slow-flow perimedullary vessels extending to the skull base, which are consistent with drainage vessels of a dural arteriovenous fistula at the craniocervical junction. This fistula was subsequently seen in both patients on selective arteriograms of the ascending pharyngeal and vertebral arteries.
磁共振成像显示，两名进行性脊髓病患者的脊髓出现肿胀和弥漫性信号改变。磁共振血管造影显示，髓周血管血流缓慢，延伸至颅底，这与颅颈交界处硬脑膜动静脉瘘的引流血管相符。随后，在两名患者的咽升动脉和椎动脉选择性动脉造影中均发现了这种瘘管。
