Brain herniation is a potentially deadly side effect of very high pressure within the skull that occurs when a part of the brain is squeezed across structures within the skull.The brain can shift across such structures as the falx cerebri, the tentorium cerebelli, and even through the foramen magnum (the hole in the base of the skull through which the spinal cord connects with the brain). Brain MRI is preferred over CT, providing superior visualization of cortical and subcortical structures, deep nuclei, and posterior fossa and brainstem structures and greater sensitivity for detection of demyelinating, neoplastic, or infectious lesions. 4.
