What are meningoceles?
A meningocele is a birth defect where there is a sac protruding from the spinal column. The sac includes spinal fluid, but does not contain neural tissue. It may be covered with skin or with meninges (the membranes that cover the central nervous system).
What is the difference between meningocele and myelomeningocele?
With meningoceles, the spinal cord has developed normally and is undamaged. The child has no neurological problems. Myelomeningocele is the most severe form of spina bifida, occurring nearly once for every 1,000 live births.
What causes meningocele adults?
Meningocele results from a developmental failure in the caudal end of the neural tube, resulting in a sac containing cerebrospinal fluid, meninges, and overlying skin.
How many forms of spina bifida are there?
There are three main types of spina bifida: spina bifida occulta, meningocele, and myelomeningocele.
Is meningocele open or closed?
A meningocele is an abnormal lump in the lower back. There are two types of meningoceles: open (skin is missing) and closed (the skin covering is intact). It is common to have parts of the spinal cord or nerves inside the lump. For both meningoceles and myelomeningoceles, the surgeon will close the opening in the back.
Is meningocele a spina bifida?
Another type of spina bifida is meningocele. With meningocele a sac of fluid comes through an opening in the baby’s back. But, the spinal cord is not in this sac. There is usually little or no nerve damage.
What is Myelocystocele?
Myelocystocele is a variety of occult spinal dysraphism that is characterized by a localized, cystic dilatation of the terminal part of the central canal that then herniates through a posterior spina bifida.
What are the complications of meningocele?
Fluid buildup and pressure in the brain (hydrocephalus) Increased chance of urinary tract infection and bowel problems. Infection or inflammation of the spinal cord. Paralysis, weakness, or sensation changes due to loss of nerve function.
Meningoceles are protrusions of the meninges through a defect or weak point in the skull or spine, usually involving the soft tissues beneath the surface of the skin. They are typically categorized into congenital, iatrogenic (e.g. following a craniotomy, sinus surgery, or as a laminectomy complication), and spontaneous.
What is included in the evaluation of meningoceles?
Postnatally, meningoceles may be evaluated by spinal ultrasonography or MRI to evaluate the spine for tethering, syringohydromyelia, and diastematomyelia (Ladino Torres and DiPietro, 2014). At centers without extensive ultrasound expertise, MRI is the study of choice, and computed tomography is used mainly to delineate bony landmarks.
What are meningoceles and spina bifida?
Meningoceles are considered to be neural tube defects and are a form of spina bifida. It is the least common type of spina bifida. Spina bifida occurs in about 1 out of every 1,000 births. To close meningoceles at the skull base or top of the spine, our surgeons may use the minimally invasive Endoscopic Endonasal Approach (EEA).
What is the prevalence of thoracic meningocele in a syndrome?
A syndrome of generalized neurofibromatosis (von Recklinghausen disease), kyphoscoliosis, and intrathoracic meningocele may occur, but thoracic meningocele as an isolated defect is much less frequent; only four pediatric cases have been reported.
