A meningocele is a protrusion of intracranial contents through a defect in the skull. Meningioceles contain meninges alone, without actual brain tissue herniating through the defect. If both brain and meninges are contained in the mass, the term meningoencephalocele is used. What is the meaning of the medical term meningocele?
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 meningocele adult?
The meningocele is a protrusion of a spinal fluid-filled sac of meninges through a bony defect in the posterior elements of the spine without associated neural tissue herniation. This is the mildest form of spina bifida cystica. It is not associated with a neurological deficit. What disabilities can meningocele cause?
Between 70% and 90% of infants born with myelomeningocele also experience hydrocephalus due to a defect at the base of the skull (Chiari malformation). Hydrocephalus is an excess buildup of spinal fluid on the brain that will cause brain damage, seizures or blindness if it is left untreated.
What is meningocele vs Myelomeningocele?
When the sac contains meninges and cerebrospinal fluid, the condition is called meningocele. In case of meningomyelocele, the sac also contains neural elements. The most severe type of spina bifida cystica is called myeloschisis, also known as myelocele. What is occipital meningocele?
Definition. A herniation of meninges through a congenital bone defect in the skull in the occipital region. [ from HPO]
Frequently Asked Questions(FAQ)
What are the clinical features of meningocele?
Symptoms of meningocele type of spina bifida include: small opening in the back. sack that’s visible at birth. membranes pushing out through the opening in the vertebrae into sack.
What is the protrusion mean?
1 : something (such as an anatomical part or excrescence) that protrudes. 2 : the act of protruding : the state of being protruded.
What is a meningocele associated with?
Recent reports indicate that meningocele is often associated with tethered cord syndrome, and those symptoms of tethered cord syndrome occur in a considerable proportion of children who had meningocele repair. Myelomeningocele is commonly associated with hydrocephalus.[1][14][3]
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 Lipomeningocele?
What is Myelocele?
In myelocele, the spinal cord is exposed so that nerve tissue lies exposed on the surface of the back without even a covering of skin or of the meninges, the membranous tissue surrounding the brain and spinal cord.
Is Meningocele hereditary?
This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most cases result from new mutations in the gene and occur in people with no history of the disorder in their family.
What does a sacral dimple mean?
A sacral dimple is a small indentation (dent) in the lower back, near the crease of the buttocks. It is a congenital condition, meaning it is there when the baby is born. Most sacral dimples do not cause any health issues. In some cases, a sacral dimple can be a sign of an underlying spinal problem.
Can a baby born with spina bifida live a normal life?
This can cause physical and mental issues. About 1,500 to 2,000 babies of the 4 million born in the U.S. every year have spina bifida. Thanks to advances in medicine, 90% of babies who have this defect live to be adults, and most go on to lead full lives.
What are the 4 types of spina bifida?
There are four types of spina bifida: occulta, closed neural tube defects, meningocele, and myelomeningocele. The symptoms of spina bifida vary from person to person, depending on the type and level of involvement.
What is tethered cord syndrome?
Tethered spinal cord syndrome is a neurological disorder caused by tissue attachments that limit the movement of the spinal cord within the spinal column. Attachments may occur congenitally at the base of the spinal cord (conus medullaris) or they may develop near the site of an injury to the spinal cord.
What is the lifespan of someone with spina bifida?
Generally, medical professionals state that about 90% of patients with SB will live past their third decade of life. However this number has increased over the years because of improvements in medical technology so it has increased the life expectancy of patients born with spina bifida.
Can babies with spina bifida move their legs?
In children with spina bifida, the nerves in the spinal canal are often damaged or improperly formed, and therefore they may not able to control the muscles properly or sometimes feel properly. Some children may be paralyzed, not able to move their legs at all, while others can stand and walk to some extent.
Why is it called Dandy Walker syndrome?
The syndrome is named after physicians Walter Dandy and Arthur Walker, who described associated signs and symptoms of the syndrome in the 1900s. The malformations often develop during embryonic stages.
What causes Myelomeningocele?
What causes myelomeningocele? The exact cause is unknown, but a lack of folic acid, exposure to viruses, exposure to radiation, and/or genetics are suspected. How is it diagnosed? It is diagnosed with prenatal blood work, amniocentesis, physical exam, and ultrasound.
What is cranium bifidum?
Cranium bifidum is an abnormal osseous defect of the calvarium through which herniation of meninges and brain tissue may occur. It occurs with midline malformations such as myelomeningocele, meningoencephalocele or dermal sinus [1].
What are the complications of Meningocele?
Risks for this surgery are:
- 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.
Is laminectomy the same as decompression?
Cervical laminectomy Laminectomy is surgery that creates space by removing the lamina — the back part of a vertebra that covers your spinal canal. Also known as decompression surgery, laminectomy enlarges your spinal canal to relieve pressure on the spinal cord or nerves.
What does contritely mean?
: feeling or showing sorrow and remorse for a sin or shortcoming a contrite criminal a contrite apology contrite sighs.
What is the medical term for protrusion?
Herniation: Abnormal protrusion of tissue through an opening.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
