What is tentorium of the brain?
The tentorium cerebelli, the second-largest dural reflection, is a crescent-shaped dura fold that extends over the posterior cranial fossa, separating the occipital and temporal cerebral hemisphere from the cerebellum and infratentorial brainstem [1,6].
What is a Tentorial?
: a bony ridge on the inner surface of the skull that marks the attachment of the tentorium.
What is the tentorium made of?
The tentorium cerebelli (Latin for “tent of the cerebellum”) is an invagination of the meningeal layer of the dura mater that separates the occipital and temporal lobes of the cerebral hemispheres from the cerebellum and brainstem.
Where is the Tentorial notch?
Structure. The tentorial notch is located between the tentorial edges and communicates the supratentorial and infratentorial spaces. This area can be divided into three spaces: anterior, middle (lateral to), and posterior to the brainstem.
Where is the tentorial notch found?
What is the cerebellar tentorium?
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.
What is a cerebellar stroke?
A cerebellar stroke is a rare condition that can affect your balance and motor skills. Since this type of stroke presents with nonspecific symptoms, receiving treatment may be delayed. This can make cerebellar strokes life-threatening. If treated early, the chance of recovery from a cerebellar stroke is high.
How long does it take to recover from a cerebellar stroke?
A cerebellar stroke is a rare condition that can affect your balance and motor skills. Since this type of stroke presents with nonspecific symptoms, receiving treatment may be delayed. This can make cerebellar strokes life-threatening. If treated early, the chance of recovery from a cerebellar stroke is high. However, full recovery can take time.
What happens when the tentorium of the brain expands?
Since the tentorium is a hard structure, if there is an expansion of the volume of the brain or its surrounding matter above the tentorium, such as because of a tumour or bleeding, the brain can get pushed down partly through the tentorium.
