Can there be meningocele in fetus without spina bifida?

Depends: This depends on how you define it. Meningoceles as they are commonly labeled originate anywhere from the neck down to the base of the spine and involve spina bifida. When a meningocele (bag of meninges) arises from the areas above the spine, it is more often labeled an encephalocoel because it usually has brain and meninges in it.

Bone defect: Form of spina bifida, meningocele, spinal fluid and meninges protrude through an abnormal vertebral opening; the malformation contains no neural elements and may or may not be covered by a layer of skin. Some individuals with meningocele may have few or no symptoms while others may experience such symptoms as complete paralysis with bladder and bowel dysfunction.
