OCCULT SPINAL
DYSRAPHISM |
Occult spinal dysraphism represents a spectrum of anomalies that all result in an abnormal attachment of the conus to neighboring structures.
- The conus may be elongated by a variety of anomalies of the spinal cord including:
- Spinal lipoma.
- Lipomeningocele.
- Diastematomyelia.
- Dorsal dermal sinus.
- Split notocord syndrome.
- There is no associated fetal hydrocephalus.
- Postnatally there may be:
- Cutaneous or subcutaneous anomalies such as an angioma, lipoma, pigmented nevus, a tuft of hair or skin dimple that demarcates the site and level of the vertebral lesion.
