In Spina Bifida Occulta, there is a midline defect of the spinal
column without protrusion of the spinal cord or meninges. Most affected
individuals are asymptomatic and lack neurological signs. In some cases, it
may be associated with patches of hair, a lipoma, discoloration of the skin,
or a dermal sinus in the midline of the low back. In meningocele, the
meninges herniate through the defect, but the spinal cord assumes normal
position in the spinal canal. The spinal cord may or may not be normal.
