Myelopathy after traumatic lumbar vertebral intraosseous arteriovenous fistula with epidural venous drainage treated with transvenous embolization

Spinal epidural arteriovenous fistulas are an uncommon entity. The authors present an interestingcase of a 48-year-old man involved in a MVC five months prior to presenting with bilateral lower extremity weakness and hypoesthesia below the knees. MRI demonstrated a flow void in the L1 vertebral body burst fracture along with a dilated basivertebral vein draining in to engorged epidural venous plexus. Angiography confirmed an intraosseous arteriovenous fistula fed by T12 and L1arteries and epidural venous drainage.
