Spinal cord arteriovenous malformations (SAVM) are rare, especially in children. This article first reported a newborn SAVM. Children with children, 38 weeks of pregnancy, the failure of natural childbirth Caesarean section. No special prenatal. At 16 weeks of gestation, the lower extremity can be examined ultrasonically. 3.5 kg at birth, Apgar scoring 1,4,7 points at 1,5,10 minutes. Lower limb involuntary movement, pain and knee reflex disappeared, ankle reflex decreased. Anal sphincter relaxation, urine easily squeezed out. Upper extremity normal, grasping, hugging and sucking reflex normal. Back skin no plaque. Admission examination, cerebrospinal fluid yellowing, but no red blood cells. Spine photos to see the upper lumbar spine between the broadened distance, a panacanamide spinal cord showed T_ (10) ~ L_2 large dura within the dura. 4 days after birth, lower extremity paresis did not improve, the line of laminectomy found intramedullary exploration of the dura mater up, cut the dura can be seen in the cauda equina and the vertebral body has a cystic lesion, the vertebral crus is flat, varicose veins obvious . Needle puncture bag, bleeding more. Stop bleeding
