What is herniation syndrome?
A cerebral herniation or brain herniation is a serious medical condition that happens when brain tissues move from one part of the brain to another adjacent part of the brain. It is usually caused when another condition causes swelling or pressure inside the brain.
What are the different 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 herniation of the brain?
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.
What is the medical term for herniation of the brain?
A brain herniation, sometimes described as a cerebral herniation, occurs when brain tissue, blood, and cerebrospinal fluid (CSF) shift from their normal position inside the skull.
What is a Transtentorial herniation?
A transtentorial herniation is the movement of brain tissue from one intracranial compartment to another. This includes uncal, central, and upward herniation.
When does Transtentorial herniation occur?
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 is the importance of Transtentorial herniation?
A transtentorial herniation is the movement of brain tissue from one intracranial compartment to another. This includes uncal, central, and upward herniation. These are life-threatening and time-critical pathologies that may be reversible with emergent surgical intervention and medical management.
Why does brain herniation cause death?
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 is kernohan notch?
Kernohan’s notch phenomenon is the ipsilateral hemiplegia caused by compression of the contralateral cerebral peduncle against the tentorial edge by a supratentorial mass. Diffusion tensor imaging (DTI) and transcranial magnetic stimulation (TMS) could be useful for exploring the state of the corticospinal tract (CST).
What is the ICD-9 code for diagnosis?
ICD-9-CM 728.89 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 728.89 should only be used for claims with a date of service on or before September 30, 2015.

What is a herniated brain?
cerebral herniation. Downward displacement of the brain (usually as a result of cerebral edema, hematoma, or tumor) into the brainstem. The resulting injury to brainstem functions rapidly leads to coma, nerve palsies, and death if treatment is ineffective.
What is a herniated disc?
Herniated disc is also known as displacement of intervertebral disc without myelopathy, herniated intervertebral disc, herniation of intervertebral disc, herniation of intervertebral disc wo myelopathy, herniation of nucleus pulposus, intervertebral disc prolapse, and prolapsed intervertebral disc without myelopathy.
