[Hematomyelia complicating a spinal dural arteriovenous fistula. Report of a case].

We report a case of hematomyelia which led to sudden onset complete paraplegia in a 74-year-old man. Hematomyelia revealed a spinal dural arteriovenous fistula at level T8-T9. Spinal hemorrhage was observed in contact with a round-shaped aneurysmal like ectasia which undoubtedly ruptured. Treatment was embolization. Spinal atrophy followed and MRI one year after embolisation visualized the involution of the pathological vessels. We discuss the pathophysiology of this hemorrhagic accident and specific anomalies of the drainage veins in these malformations.
