Meningocele is a type of neural tube defect (NTD) that occurs in newborns. The condition involves the protrusion of the meninges, which are the protective coverings of the brain and spinal cord, through a defect in the spinal column. Unlike other forms of spina bifida, meningocele does not involve the spinal cord itself in the sac, which can be an essential factor in its prognosis and treatment.
