Herniation
Chapter: 28
In cases of increased intracranial pressure, portions of the brain, most closely located to "exit" areas, will be pushed into those openings and create damage by compression and self compression. Most important, herniation of cerebellar tonsil(s) into foramen magnum with compression of medulla oblongata, and herniation of uncus of hippocampus (medial temporal lobe) into tentorial incisure, compressing the midbrain from one or both sides.
