Cervical cord infarction caused by dissection of the intracranial segment of the vertebral artery

Abstract

Cervical cord infarction is uncommon but has been increasingly reported as a complication of vertebral artery dissection (VAD). A 54-year-old woman presented with neck pain and neurological deficit following sudden neck movement. Radiological findings suggested cervical cord infarction in the anterior spinal artery territory at the C5-C6 vertebral level and dissection of the intracranial segment of the right vertebral artery. Cervical cord infarction due to VAD is usually caused by dissection of its extracranial segment. The present case indicates that dissection of the intracranial segment of the vertebral artery can also cause cervical cord infarction.
