The tentorial notch (also known as the tentorial incisure or incisura tentorii) refers to the anterior opening between the free edge of the cerebellar tentorium and the clivus for the passage of the brainstem. The midbrain continues with the thalamus of the diencephalon through the tentorial notch. Well defined fat lesion is again demonstrated on the tentorium cerebelli expressing high T1 and FLAIR signal.

ten·to·ri·um ce·re·bel·li. ( ten-tōr'ē-ŭm ser'ĕ-bel'ī) [TA] A strong fold of dura mater roofing over the posterior cranial fossa with an anterior median opening, the tentorial notch, through which the midbrain passes; the tentorium cerebelli is attached along the midline to the falx cerebri and separates the cerebellum from the basal surface of the occipital and temporal lobes of the cerebral hemisphere.

The cerebellar tentorium is an arched lamina, elevated in the middle, and inclining downward toward the circumference. It covers the top of the cerebellum, and supports the occipital lobes of the brain. Its anterior border is free and concave, and bounds a large oval opening, the tentorial incisure, through which pass the cerebral peduncles. The tentorium cerebelli (plural: tentoria cerebellorum) is the second largest dural fold after the falx cerebri.

Tentorial/Peritentorial Subdural Hemorrhage – rare, but this is what they look like on CT. They may resemble intraparenchymal bleed on CT but MRI can confirm exact location with regard to the tentorium. As a reminder, the tentorium is an extension of the dura; it separates the cerebellum from the inferior portion of the occipital lobes.

The tentorium cerebelli - an infolding of the dura mater - forms a tent-like sheet which separates the cerebrum (brain) from the cerebellum The falx cerebri and tentorium cerebelli, protrusions of fused inner and outer dural membranes, confine the anterior, middle, and posterior fossae of the skull.Outer (superior sagittal) and inner (inferior sagittal) venous channels, found in split layers of the dura, drain blood from the superficial and deep regions of the central nervous system, respectively, into the jugular veins. Examination of histological sections of 38 fetuses at 10-16 weeks gestational age (GA) demonstrated that: (1) the superior petrosal sinus passed posterosuperiorly through the tentorium cerebelli and, distant and lateral to both the cerebellum and internal ear, drained into the transverse sinus; (2) the superior sagittal sinus was underdeveloped, and the inferior sagittal sinus was not yet Increased bowing of the tentorium in patients with idiopathic intracranial hypertension compared with controls is a new observation, lending itself to new hypotheses on the nature and localization of elevated intracranial pressure in idiopathic intracranial hypertension.

Tentorium. The tentorium cerebelli or cerebellar tentorium (Latin: “tent of the cerebellum”) is an extension of the dura mater that separates the cerebellum from the inferior portion of the occipital lobes. The tentorium cerebelli is an arched lamina, elevated in the middle, and inclining downward toward the circumference. a strong fold of dura mater roofing over the posterior cranial fossa with an anterior median opening, the tentorial notch, through which the midbrain passes; the tentorium cerebelli is attached along the midline to the falx cerebri and separates the cerebellum from the inferior surface of the occipital and temporal lobes of the cerebral hemisphere.
