Posterior cervical spinal cord infarction complicating the treatment of an intracranial dural arteriovenous fistula embolization. Case report.
Acute ischemic infarction of the posterolateral bulbomedullary junction occurred in a 28-year-old man who underwent arterial embolization for the treatment of an intracranial dural arteriovenous malformation. The migration of the embolic agent in the posterior spinal artery via a peripheral anastomosis between the middle meningeal artery and the posterior meningeal artery was responsible for this complication. The cast of glue in the radiculopial system at the upper cervical level was visible on computed tomography scanning, and magnetic resonance imaging demonstrated circumscribed signal changes and restricted diffusion in the arterial territory of the bulbomedullary junction. The authors discuss the anatomical, clinical, and technical issues of this rare complication.
