Uncal herniation occurs when a cerebellar tonsil shifts through the foramen magnum. the cingulate gyrus shifts under the falx cerebri. the diencephalon shifts from the middle fossa straight downward through the tentorial notch into the posterior fossa. the hippocampal gyrus shifts from the middle fossa through the tentorial notch into the posterior fossa. Uncal herniation (hippocampal herniation, lateral mass herniation) occurs when the uncus or hippocampal gyrus (or both) shifts from t...
