What is a Subfalcine 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 does Subfalcine mean?
Subfalcine. The brain tissue moves underneath a membrane known as the falx cerebri in the middle of the brain. Brain tissue ends up being pushed across to the other side. This is the most common type of brain herniation.
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.
How does tonsillar herniation cause death?
Cerebellar Tonsillar Herniation Increased pressure in the posterior fossa forces the cerebellar tonsils through the foramen magnum. These will compress the lower part of the brain stem and upper cervical cord, resulting in life-threatening consequences.
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.
How is Subfalcine herniation treated?
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.
How do you fix a brain herniation?
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.
What is 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.
