Tentorial herniation

Radiology. 1976; 123: 93-96. 10 Dec 2010 Bilateral uncal herniation is typically seen in brain death. Transtentorial herniation can cause occipital infarcts resulting in visual loss.

What are synonyms for tentorial herniation? Descending tentorial herniation (DTH) can be diagnosed by computed tomography. Encroachment upon the lateral aspect of the suprasellar cistern is an early sign of impending tentorial herniation.

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.

Epidural Hematoma Valsalva Five patients (4 male and 1 female) were observed to have capsular and thalamic infarction ascribed to descending transtentorial herniation (DTH) caused by head injury. A lucid interval immediately after the trauma and the presence of an epidural hematoma (EDH) characterized all five cases. At the time of hospitalization consciousness was seriously impaired and signs of cerebral herniation Dear Editor, Since the original description of ipsilateral occipital-lobe infarction from a tentorial herniation in 1920, 1 pathologic and neuroradiologic studies have suggested posterior cerebral artery (PCA) impingement against the leading edge of the tentorial incisura as the underlying mechanism. Central herniation: Both temporal lobes herniate through the Tentorial notch because of bilateral mass effects or diffuse brain edema 27.

Descending tentorial herniation (DTH) can be diagnosed by computed tomography. En- croachment upon the lateral aspect of the suprasel-. Transtentorial herniation is the unilateral or bilateral displacement of the parahippocampal gyrus of the occipital lobe(s) beneath the tentorium cerebelli, resulting Ascending transtentorial herniation. The cerebellum and the brainstem move upward through a notch in a membrane called the tentorium cerebelli. Cerebellar Subset of transtentorial herniations.

Traumatic Isolated Brain Stem Hematoma: A Case Report Presenting with Hemiparesis 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.

Although the head computed tomography (CT) revealed a tentorial blood suffusion, the patient did not experience neurologic damage. Dear Editor, Since the original description of ipsilateral occipital-lobe infarction from a tentorial herniation in 1920, 1 pathologic and neuroradiologic studies have suggested posterior cerebral artery (PCA) impingement against the leading edge of the tentorial incisura as the underlying mechanism. However, the rare cases of isolated contralateral PCA infarction have not been explained.

There may be herniation also of both temporal unci and parahippocampal gyri as well as the lingual gyrus and isthmus of the gyrus Radiographically, downward herniation is characterized by obliteration of the suprasellar cistern from temporal lobe herniation into the tentorial hiatus with associated compression on the cerebral peduncles. Upwards herniation, on the other hand, can be radiographically characterized by obliteration of the quadrigeminal cistern. If a herniation is complete, it depresses the posterior cerebral artery along the entire length of the tentorial notch (Fig.

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. Tentorial incisure.

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.
