- Diastematomyelia is an uncommon congenital anomaly characterized pathologically by sagittal clefting of the spinal cord or filum terminale, with each half of the spinal cord being surrounded by a dural sac.
- This disorder is usually caused by either a fibrous bony septum or an osteocartilaginous septum.
- Diastematomyelias are most frequently found in the lumbar spine, followed by the thoracic region.
- Some form of an associated congenital anomaly, or dysraphism, of the vertebral column is a constant feature.
