The split-cord malformation (or diastematomyelia) represents a sagittal cleft of the spinal cord into two hemicords that can be enclosed in single or separate dural sheaths and separated by a fibrous or osteocartilaginous septum, respectively . Up to 85% have associated spinal anomalies, the most common being low-lying conus medullaris and thickened filum terminale . A myelomeningocele involving one of the hemicords (i.e. hemimyelomeningocele) is seen in up to 41% of cases .
