What is a Meningocele cyst?
What is a Meningocele cyst?
This is seen as mild to moderate and is the least common. A small, moist sac or cyst protrudes through the gap in the spine. This sac contains a portion of the spinal cord membrane (meninges) and some spinal fluid. The sac may be covered with skin or part of the spinal cord membrane.
What is occipital Meningocele?
Definition. A herniation of meninges through a congenital bone defect in the skull in the occipital region. [ from HPO]
What is the difference between meningocele and myelomeningocele?
Meningocele typically causes mild problems, with a sac of fluid present at the gap in the spine. Myelomeningocele, also known as open spina bifida, is the most severe form.
What causes a meningocele?
Meningocele results from a failure to develop the caudal end of the neural tube resulting in a protrusion that contains cerebrospinal fluid, meninges, overlying skin, and does not have the spinal cord as its content. Anterior meningocele is usually presacral in location.
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.
Can a meningocele be removed?
Surgery. Treating the meningocele involves closing the overlying meninges and the skin. Surgery is performed within a day or two of birth, and is necessary to prevent infection and to protect the exposed area of the spine.
What do you need to know about congenital meningoceles?
Congenital spinal meningoceles are developmental anomalies of meningothelial elements displaced into the skin and subcutaneous tissues. Please refer on menigocele article for a broad overview of all types of this condition. Pathology. It is defect of the neural tube, an embryonic structure that gives rise to the spinal cord and vertebral column.
What kind of lesion is an intrasacral meningocele?
Intrasacral meningoceles result from arachnoid diverticulum that has herniated out of a congenital defect in the dura but that remains confined within the sacral canal 7. Typically seen as a hypoattenuating lesion (isodense to CSF) enlarging the sacral thecal sac, which may displace the nerve roots.
What kind of Meningocele is the lateral thoracic?
Lateral thoracic meningoceles are a type of spinal meningocele. As with any meningocele, it results from herniation of the meninges through a foramen or a defect in the vertebral column.
Is there a differential diagnosis for spinal acquired meningoceles?
They are typically categorized into congenital, iatrogenic (e.g. following a craniotomy, sinus surgery, or as a laminectomy complication), and spontaneous. A differential diagnosis for both spinal and cranial acquired meningoceles are pseudomeningoceles, which are CSF collections not lined by dura.
