congenital malformations involving an abnormal closure and development
 Spinal dysraphism is a general term to describe congenital malformations involving an abnormal closure and development of the neural tube, its neighboring structures and the posterior midline anatomy. 
Diastematomyelia means clefting of the spinal cord. The spinal cord and the intradorsal nerve roots are subdivided into two columns by a mass attached anteriorly to the vertebral body and posteriorly to the dura mater. This mass may be a bony, fibrous or cartilaginous septum that partially or completely subdivides the vertebral canal. The neural elements usually present a distinct arachnoid mater but have a common dura mater. Diastematomyelia may be localized to a single vertebra or extend to several vertebral segments. The cleft is most commonly located (70-80%) at the lower thoracic or upper lumbar regions, but it may occur at any level
