Abstract:
Spinal dural arteriovenous fistulas are rare abnormal connections of artery and vein within the dura, at the level of the intervertebral foramen. A 57-year-old male developed weakness in both lower extremities and sphincteric dysfunction, which had stepwisely, progressive and fluctuating course since 6 months ago. He showed areflexia in both ankle & right knee. T-spine MRI showed high signal intensity with ill defined margin in T2WI and intensely enhanced by con-trast agent through lower thoracic and lumbosacral spinal cord. Selective spinal angiography revealed a dural arteriove-nous fistula with a nidus at thoracolumbar vertebral level, supplied by the internal iliac artery and enlarged medullary veins. Superselective angiographic embolization was done. Clinically, his symptoms has been ameliorated. We report a rare case of thoracic myelopathy due to spinal dural arteriovenous fistulas exclusively supplied by the branches of internal iliac artery.
