Tentorial herniation is the most common and most important form of brain herniation (10, 12, 15). In descending herniation caused by supratentorial mass lesions, the uncus and parahippocampal gyri herniate downward through the incisura, and in ascending herniation resulting from infratentorial masses, the superior part of the cerebellum may herniate upward through the incisura.

It usually occurs with other types of downward herniation such as uncal herniation. Clinical manifestati You can support the work of campbellteaching, at no cost whatsoever to yourself, if you use the link below as your bookmark to access Amazon.

The tentorium is an extension of the dura mater that separates the cerebellum from the cerebrum. There are two major classes of herniation: supratentorial and infratentorial. Supratentorial refers to herniation of structures normally found above the tentorial notch, and infratentorial refers to structures normally found below it.

The patient's status markedly improved after decompressive anterior temporal lobe resection. To our knowledge a similar case has not yet been reported in the literature. The cerebellum occupies the posterior portion of the tentorial notch.
