Abstract

The spinal cord is covered by a functionally important pial arterial network described by Adamkiewicz in 1881 under the name of vasocorona. This arterial network loosely interconnects the anterior and posterior longitudinal axes and may become enlarged under pathological circumstances. We report here a case of moyamoya syndrome in a 2-year-old boy with bilateral vertebral artery occlusion, in which the collateral supply to the basilar artery occurred via a dilated portion of the vasocorona of the upper cervical spinal cord.
