17 Aug 2018 Brain herniation syndromes can be broadly divided into 4 categories: (1) cingulate (or subfalcine), (2) transtentorial herniation, (3) uncal

In severe cases, cerebral oedema, tentorial herniation, respiratory arrest and cerebral hypoxia can ensue 16 as postmortem findings confirmed in two patients of  A. Transtentorial (uncal) herniation is protrusion of the brain through the.

The displaced uncus typically puts pressure on the midbrain and the oculomotor nerve (CN III). A central herniation involves the displacement of the diencephalon and cortical structures through the tentorial notch.

Brain Herniation Transtentorial herniation. The medial temporal lobe is squeezed by a unilateral mass across and under the tentlike Subfalcine herniation. The cingulate gyrus is pushed under the falx cerebri by an expanding mass high in a cerebral Central herniation. Both temporal lobes

This is also known as a transtentorial herniation since it occurs across the tentorium cerebelli. transtentorial herniation downward displacement of medial brain structures through the tentorial notch by a supratentorial mass, exerting pressure on the underlying structures, including the brainstem; this is a life-threatening situation because of pressure on the third cranial nerve, with symptoms including dilated, nonreactive pupils, ptosis, and a decreased level of consciousness.

Supratentorial refers to herniation of structures normally found above the tentorial notch, and infratentorial refers to structures normally found below it. Brain herniation occurs when increased intracranial pressure causes the abnormal protrusion of brain tissue through openings in rigid intracranial barriers (eg, tentorial notch).

Thank you.If in 2015-09-18 Central herniation: Both temporal lobes herniate through the tentorial notch because of bilateral mass effects or diffuse brain edema. Upward transtentorial herniation: This type can occur when an infratentorial mass (eg, tumor in the posterior fossa, cerebellar hemorrhage) compresses the brain stem, kinking it and causing patchy brain stem ischemia.

When tentorial herniation occurred, the direct pressure of both unci fell upon the posterior cerebral arteries on both sides, or these arteries became stretched and kinked. Ischemic changes consequently occurred in the occipital lobes, which depend for their blood supply on these arteries.

The cerebellum occupies the posterior portion of the tentorial notch. Uncal herniation occurs when rising intracranial pressure causes portions of the brain to flow from one intracranial compartment to another; this is a life-threatening neurological emergency and indicates the failure of all adaptive mechanisms for intracranial compliance.
