The term herniation refers to compression of the brain due to lack of available space and increased intracranial pressure. Such a herniation is always a potentially life-threatening situation. Depending on the location of the herniation of brain tissue, different forms of herniation are distinguished:
Subfalcine herniation
This involves herniation and displacement of the Cingulate gyrus toward the contralateral side.
Uncal herniation
In uncal herniation, the Uncus, or the anterior portion of the temporal lobe, is displaced into the tentorial notch[^2].
Herniation into the foramen magnum
This involves herniation of the cerebellar tonsils into the Foramen magnum, with compression of the brainstem.
Upward transtentorial herniation of the cerebellum
In this form of herniation, the cerebellum herniates upward, resulting in brainstem compression[^1].
