Subfalcine herniation causes
Web11 Jun 2024 · In subfalcine herniation, the ipsilateral cingulate gyrus moves beneath the falx cerebri by pushing corpus callosum downwards due to a factor that causes supratentorial mass effect. If the pressure increase persists, the contralateral cingulate gyrus becomes compressed by herniated tissue. Web31 May 2024 · Herniation occurs when brain tissue is displaced across a structure within the cranium. 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.
