Extra cranial vertebrovertebral arteriovenous fistulas (VV AVF) are commonly associated with trauma. Their presentation may vary from palpable thrill and myelopathy or myeloradiculopathy. Sudden onset paraparesis is rare.

Keywords: Embolization; NF 1; neurofibromatosis type 1; vertebrovertebral arteriovenous fistula.
