What is a typical characteristic of meningocele?

Meningocele is a type of spina bifida, which is a neural tube defect that occurs when the spinal column does not close completely. A typical characteristic of meningocele is indeed the protrusion of the meninges. In this condition, the protective membranes surrounding the spinal cord (the meninges) form a sac that protrudes through a defect in the spine. This sac can sometimes contain cerebrospinal fluid but does not include the spinal cord itself.

This distinction is crucial because it differentiates meningocele from other forms of spina bifida, such as myelomeningocele, where both the spinal cord and meninges protrude. Recognizing this specific characteristic aids in understanding the potential complications and necessary interventions for individuals diagnosed with meningocele, as the spinal cord remains protected within the bony spine, generally leading to a better prognosis compared to myelomeningocele.

The presence of a visible sac containing the meninges also aligns with the clinical presentation observed in individuals with this condition, making option B the correct choice.
