A 60-year-old woman had transient weakness of the legs and urinary retention for six weeks. She presented with a gait disorder and was admitted to the hospital. She showed symptoms of paraplegia, tingling in the lower extremities, dysuria. She underwent an MRI, and T2-weighted images showed an enlargement of the thoracolumbar spinal cord and high intensity signal from Th3 to the medullary cone, and a contrast-enhanced T1-weighted image showed abnormal vessels anterior to the spine cord. Cervical and spinal angiography documented a dural arteriovenous fistula at the craniocervical junction that was fed by the right vertebral artery and the right ascending pharyngeal arteries and drained into the perimedullary veins. Surgical therapy improved her symptoms and MRI images. Craniocervical junction DAVF with thoracic-medullary cones lesion is rare.
一名60岁女性出现腿部短暂无力和尿潴留六周。她表现出步态障碍并入院。她有截瘫症状、下肢刺痛、排尿困难。她接受了磁共振成像（MRI）检查，T2加权图像显示胸腰段脊髓增粗，从胸3至脊髓圆锥呈高信号，T1加权增强图像显示脊髓前方有异常血管。颈部和脊髓血管造影证实颅颈交界处存在硬脊膜动静脉瘘，由右椎动脉和右咽升动脉供血，并引流至脊髓周围静脉。手术治疗改善了她的症状和MRI图像。伴有胸髓-脊髓圆锥病变的颅颈交界处硬脊膜动静脉瘘很罕见。
