title: Paravertebral arteriovenous fistulas presenting acute epidural hematoma associated with paraplegia.
abstract: We report a unique case of paravertebral arteriovenous fistulas (PVAVF) presenting with acute epidural hematoma produced by dilated venous pouch. The involved level in this patient makes this an extremely rare case. The main feeding artery was the right thyrocervical trunk and the dilated venous pouch was the posterior internal venous plexus around the upper thoracic spine. The etiology of this abnormal arteriovenous communication remains unclear. This case demonstrates that a venous ectasic pouch comprises important etiological angioarchitecture of radiculopathy and myelopathy in PVAVF.
