△颈部CTA源图像多平面重建：颈部椎管内局部可见畸形血管影（红箭）

△Multiplanar reconstruction images from the cervical CTA source images: a vascular malformation within the cervical spinal canal (red arrow)

△MRI：T2WI于颈髓周围检测到异常血液流空影；颈髓肿胀，其内可见出血混杂信号，T1WI呈等低混杂信号，T2WI呈高低混杂信号

△MRI：T2WI showed an abnormal blood flow-void effect in the cervica subarachnoid space (red arrow); the cervical spinal cord was swelling and had an internal hemorrhage with iso-hypointense signal on T1WI and iso-hyperintense signal on T2WI

△DSA：颈部脊髓动静脉畸形（红箭），由右侧椎动脉分支供血（橙箭），主要引流静脉（蓝箭）汇入颅内静脉窦

△DSA showed a cervical spinal cord arteriovenous malformation (red arrow); its blood supply artery originated from a branch of the right vertebral artery (orange arrow) and the main drainage vein (blue arrow) finally joined into the intracranial venous sinus
