摘要: We report a case of 48-year-old man with chronic back pain attributed to discogenic lumbar radiculopathy who underwent fluoroscopy-guided L2–3 interlaminar epidural steroid injection. 4 h later, he developed acute paraparesis, sensory loss below T10 level and urinary retention. MRI the thoracic spine revealed diffuse abnormal T2/FLAIR signal extensive vascular flow voids. A spinal dural arteriovenous fistula was confirmed on angiography. Embolization resulted in significant improvement symptoms. review previously reported cases current understanding pathophysiology this complication. All had symptom onset several hours after procedure. There seems be trend toward better outcomes earlier treatment.
