Treatment may involve:
Placing a drain into the brain to help remove cerebrospinal fluid (CSF) Medicines to reduce swelling
, especially if there is a brain tumor. Medicines that decrease brain swelling, such as mannitol, saline, or other diuretics.
Can you recover from brain herniation?
When herniation occurs, it
further lowers the chance of recovery
. The outlook varies, depending on where in the brain the herniation occurs. Without treatment, death is likely. There can be damage to parts of the brain that control breathing and blood flow.
Is brain herniation reversible?
Brain herniation is potentially reversible with appropriate and timely therapy
. Reversal of transtentorial herniation has been observed in 50–75 % of adult patients with either TBI [58] or with supratentorial mass lesions [59].
What is the most common type of brain herniation?
Subfalcine hernia, also known as midline shift or cingulate hernia
, is the most common type of cerebral hernia. It is generally caused by unilateral frontal, parietal, or temporal lobe disease that creates a mass effect with medial direction, pushing the ipsilateral cingulate gyrus down and under the falx cerebri.
What are the types of brain herniation?
- Subfalcine herniation.
- Transalar (transsphenoidal) herniation.
- Transtentorial uncal herniation.
- Central (trans-tentorial) herniation (descending and ascending)
- Cerebellar tonsillar herniation.
- Transcalvarial herniation.
What happens during brain herniation?
A brain herniation is typically the
result of swelling in the brain
. The swelling puts pressure on brain tissues (referred to as increased intracranial pressure), causing the tissue to be forced away from its normal positon.
What herniation means?
:
to protrude through an abnormal body opening
: rupture a herniated intervertebral disk.
What causes a brain herniation?
Brain herniation occurs when
something inside the skull produces pressure that moves brain tissues
. This is most often the result of brain swelling or bleeding from a head injury, stroke, or brain tumor. Brain herniation can be a side effect of tumors in the brain, including: Metastatic brain tumor.
Which brain herniation is the most life-threatening?
Central herniation
Downward herniation can stretch branches of the basilar artery (pontine arteries), causing them to tear and bleed, known as a Duret hemorrhage. The result is usually fatal.
What causes Tentorial herniation?
Upward transtentorial herniation can occur when an infratentorial mass (eg, tumor in the posterior fossa, cerebellar hemorrhage)
compresses the brain stem
, kinking it and causing patchy brain stem ischemia. The posterior 3rd ventricle becomes compressed.
What does Subfalcine herniation mean?
Subfalcine herniation is
the most common form of intracranial herniation
and occurs when brain tissue is displaced under the falx cerebri. The cingulate gyrus is herniated under the falx, and if progression occurs, other areas of the frontal lobe are involved.
What is the medical term for herniation of the brain?
Encephal/o/cele
: Herniation of brain tissue through cranial fissure. Kele or –cele = abnormal protrusion or swelling.
What is tonsillar herniation of the brain?
Tonsillar herniation is
the movement of brain tissue from one intracranial compartment to another
, specifically the movement of the cerebellar tonsils through the foramen magnum. This is a life-threatening and time-critical pathology that may be reversible with emergent surgical intervention and medical management.
Can your brain collapse?
Scientists believe that a number which is known as Graham’s Number is so long that if you try to remember then your brain
may collapse
and the same can lead to a formation of a black hole in the brain.
What is a brain compression?
Compression of the brain is a
condition in which something increases the amount of pressure pushing on the brain
, which can damage brain tissue.
What should brain pressure?
For the purpose of this article, normal adult ICP is defined as
5 to 15 mm Hg (7.5–20 cm H
2
O)
. ICP values of 20 to 30 mm Hg represent mild intracranial hypertension; however, when a temporal mass lesion is present, herniation can occur with ICP values less than 20 mm Hg [5].
