Anterior spinal artery syndrome may be caused by a variety of events, such as lesions
secondary to bleeding and ischemia affecting the anterior portion of the spinal cord. The
usual clinical picture involves diffuse or radicular pain below the level of the lesion, with
loss of sensitivity on the surface but preservation of proprioception and sensitivity to
vibration, plus paraparesis and loss of sphincter control. We report the case of a 39-yearold
man who developed sudden neck pain radiating to the arm within a few hours of
suffering tetraplegia with compromised airways. Images showed a herniated
posterolateral cervical disk and extensive infarction of the cervical spinal cord. The
possible causes of anterior spinal artery syndrome, including the relationship between
spinal infarction and a herniated intervertebral disk, are discussed.
