What is the medical term for herniation of the brain?
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 does herniation of the brain mean?
Expand Section. 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 term means herniation of part of the brain through an opening in the skull?
Cerebral herniation. MRI showing injury due to brain herniation. Specialty. Neurology, neurosurgery. Brain herniation is a potentially deadly side effect of very high pressure within the skull that occurs when a part of the brain is squeezed across structures within the skull.
What are the types of herniation?
Brain herniation is classified as follows:
- Subfalcine herniation.
- Transalar (transsphenoidal) herniation.
- Transtentorial uncal herniation.
- Central (trans-tentorial) herniation (descending and ascending)
- Cerebellar tonsillar herniation.
- Transcalvarial herniation.
What causes Subfalcine herniation?
Subfalcine herniation is noted in many conditions that cause an increase in one of the three compartments within the skull: Increased brain volume due to tumor, hemorrhage, or edema. Increased cerebral spinal fluid volume due to hydrocephalus. Increased blood volume due to increased cerebral blood flow.
What causes herniation?
Disk herniation is most often the result of a gradual, aging-related wear and tear called disk degeneration. As you age, your disks become less flexible and more prone to tearing or rupturing with even a minor strain or twist. Most people can’t pinpoint the cause of their herniated disk.
Can you survive brain coning?
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. This can rapidly lead to death or brain death.
What does Subfalcine herniation mean?
Herniation occurs when brain tissue is displaced across a structure within the cranium. Subfalcine herniation is the most common form of brain herniation and occurs when brain tissue is displaced under the falx cerebri.
What causes Tentorial herniation?
Brain herniation occurs when increased intracranial pressure causes the abnormal protrusion of brain tissue through openings in rigid intracranial barriers (eg, tentorial notch).
What is the medical term for brain herniation?
See Brain herniation, Cerebellar herniation, Disk herniation. Protrusion of an anatomic structure (e.g., intervertebral disc) from its normal anatomic position. The displacement of body tissue through an opening or defect. Downward displacement of the brain (usually as a result of cerebral edema, hematoma, or tumor) into the brainstem.
What is the medical definition of central herniation?
Pressure-induced prolapse of part of the brain into adjacent spaces, which occurs when the brain is under high pressure. Coma, paralysis, unilateral dilated pupil. Head injury, primary or metastatic brain tumour, bacterial meningitis, brain abscess. Cerebellar herniation, uncal (temporal) herniation, transtentorial herniation.
What causes an extracranial hernia in the brain?
An extracranial herniation (4) is when the brain tissue pushes through an opening in the cranial cavity formed by trauma or at a surgical site. It is also known as a transcalvarial herniation. A brain herniation is a consequence of raised intracranial pressure where the force pushes the brain tissue in a specific direction and angle.
Which is the best definition of a subfalcine herniation?
Pressure-induced prolapse of part of the brain into adjacent spaces, which occurs when the brain is under high pressure. Coma, paralysis, unilateral dilated pupil. Head injury, primary or metastatic brain tumour, bacterial meningitis, brain abscess.
Which is the best definition of brain hernia?
brain herniation. Pressure-induced prolapse of part of the brain into adjacent spaces, which occurs when the brain is under high pressure. Coma, paralysis, unilateral dilated pupil. Head injury, primary or metastatic brain tumour, bacterial meningitis, brain abscess. Cerebellar herniation, uncal (temporal) herniation, transtentorial herniation.

Pressure-induced prolapse of part of the brain into adjacent spaces, which occurs when the brain is under high pressure. Coma, paralysis, unilateral dilated pupil. Head injury, primary or metastatic brain tumour, bacterial meningitis, brain abscess.
What causes a hernia of the uncus in the brain?
transtentorial herniation. A herniation of the uncus and adjacent structures into the incisure of the tentorium of the brain. It is caused by increased pressure in the cranium.
