Living with Myelomeningocele

The most serious form of spina bifida, in which part of the spinal cord and nerves push out through an opening in the spine.

Understanding Myelomeningocele

Myelomeningocele is the most serious form of spina bifida, in which the spine and spinal cord do not form correctly before birth.

Parts of the spinal cord and nerves pop out through an open part of the spine, which damages the spinal cord and nerves. This can reduce feeling and leg movement below the opening and affect bladder and bowel control. Many children develop extra fluid around the brain (hydrocephalus). It can be noticed during pregnancy or at birth.

Signs & symptoms

GARD doesn't list a detailed symptom list, but the summary describes these features:

  • Less ability to feel sensation below the opening
  • Less leg movement
  • Trouble controlling the bladder
  • Trouble controlling the bowels
  • Extra fluid around the brain (hydrocephalus)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Spina Bifida Association may keep lists of experts for this condition.
