What is Nasofrontal encephalocele?
What is Nasofrontal encephalocele?
Definition: Characteristic sac-like protrusion of brain and meninges through an osseous cranial defect resulting from incomplete neural tube closure during fetal development. AKA: (Latin) cranium bifidum, nasal encephalocele [1], meningocele, meningoencephalocele, transsphenoidal encephalocele, basal encephalocele [3].
What is Frontoethmoidal encephalocele?
Frontoethmoidal encephaloceles are second only to occipital encephaloceles in terms of frequency, representing approximately 15% of all encephaloceles. They represent meninges or brain tissue herniating through a cranial defect in the anterior cranial fossa and typically result in facial deformity.
What is the difference between meningocele and encephalocele?
A Meningocele is like an encephalocele but only contains the cerebrospinal fluid and meninges and the sac protrudes from the spinal column.
What is the difference between cephalocele and encephalocele?
Cephalocele is a generic term defined as a protrusion of the meninges with or without brain tissue through a defect in the skull. A meningocele is a protrusion of only meninges and cerebrospinal fluid (CSF). An encephalocele is a protrusion of meninges, CSF, and brain tissue.
What is the reason for encephalocele?
Encephalocele happens when the neural tube does not close completely during pregnancy. The result is an opening anywhere along the center of the skull from the nose to the back of the neck, but most often at the back of the head (pictured), at the top of the head, or between the forehead and the nose.
What is the meaning of encephalocele?
Encephalocele is a neural tube defect characterized by sac-like protrusions of the brain and the membranes that cover it through openings in the skull. These defects are caused by failure of the neural tube to close completely during fetal development.
What is anterior encephalocele?
Anterior encephaloceles are rare congenital abnormalities characterized by herniation of intracranial components through the cranial and facial bones due to a defect of closure of the anterior neuropore of the neural tube.[7] Frontoethmoidal meningoencephaloceles are common in Southeast Asian countries, with an …
What is an encephalocele?
Encephalocele is a sac-like protrusion or projection of the brain and the membranes that cover it through an opening in the skull. Encephalocele happens when the neural tube does not close completely during pregnancy.
What is meningocele encephalocele?
A meningocele is an encephalocele that contains only the meninges and cerebral spinal fluid. These types of defects have a much better prognosis than those in which brain tissue also protrudes into the sac.
How do you describe encephalocele?
What does cephalocele mean?
The term cephalocele, in a restrictive sense, is defined as a protrusion of part of the cranial contents through a congenital opening in the cranium, typically covered with skin or mucous membrane.
What is a cephalocele?
A cephalocele is defined as a herniation of cranial contents through a defect in the skull.
