ABSTRACT
Spinal dural arteriovenous fistula (SDAVF) is rare but still the most commonly encountered vascular malformation of the spinal cord. A 31-year-old male developed gait disturbance due to weakness of his lower extremities, voiding difficulty and sexual dysfunction with a progressive course since 3 months. He showed areflexia in both knees and ankles. Electromyographic findings were suggestive of multiple root lesions involving bilateral L2 to S4 roots of moderate degree. Magnetic resonance images showed high signal intensity with an ill-defined margin in T2-weighted images and intensely enhanced by a contrast agent through the lumbosacral spinal cord. Selective spinal angiography confirmed a dural arteriovenous fistula with a nidus at the L2 vertebral level. After selective endovascular embolization, his symptoms drastically improved except sexual dysfunction. We report a rare case of cauda equina syndrome due to spinal arteriovenous fistula with drastic improvement after endovascular embolization.
