What is spina bifida meningocele?

Spina bifida meningocele occurs when the spinal arch has a defect and a sac formed by the meninges protrudes through that gap, filled with cerebrospinal fluid, but without spinal cord or nerve roots inside the sac. The sac, consisting of CSF and meninges, is the key feature, and the spinal cord remains in its normal position. That description matches an extensive spinal opening with an exposed pouch of CSF and meninges. In contrast, a sac that contains spinal cord and nerve roots would indicate myelomeningocele, which involves neural tissue in the protruding sac. Occulta presents with no visible sac, and a vague statement about vertebrae alone lacks the defining feature of a meningocele.
