•A meningocele, a type of spina bifida, is a sac that contains meninges and CSF protruding outside the vertebrae. The spinal cord is not involved and therefore, there is usually no long-term neurological damage.
•The meningocele appears as a protruding mass at the center of the lumbar region. The protrusion may be covered by a layer of skin or only a clear dura matter.
•Myelomeningocele is a herniation of the spinal cord, meninges, and CSF into a sac that protrudes through a defect in the vertebral arch. The nerves are often exposed and at risk for developing meningitis.
