What are brain cisterns?

What are brain cisterns?

The subarachnoid cisterns are spaces formed by openings in the subarachnoid space, an anatomic space in the meninges of the brain. The space is situated between the two meninges, the arachnoid mater and the pia mater. These cisterns are filled with cerebrospinal fluid.

What is Interpeduncular cistern?

The interpeduncular cistern is a cone-shaped cistern situated between the cerebral peduncles and the mesencephalic and diencephalic leaflets of the LM at the confluence of the supra- and infratentorial compartments of the subarachnoid space (Rhoton, 2000f; Lü and Zhu, 2005a; Sufianov et al., 2009).

What is Cisterna pontis?

Definition. A large, fluid-filled cistern found on the ventral aspect of the pons. Supplement. It occurs as a large space filled with cerebrospinal fluid.

What is superior cerebellar cistern?

The superior cistern (cistern of great cerebral vein, quadrigeminal cistern, Bichat’s canal) is a dilation as a subarachnoid cistern of the subarachnoid space around the brain. It lies between the splenium of the corpus callosum and the superior surface of the cerebellum.

How do cisterns work?

The collection process usually starts on a rooftop where gravity pulls rainwater towards pipes leading to a cistern tank. Water passes through mesh screens to prevent large debris from entering the tank. The collected water is stored underground where temperature changes are less likely to be an issue.

Where is the Cerebellomedullary cistern?

The opening in the subarachnoid space of the brain created by a separation of the arachnoid and pia mater. This large space is filled with cerebrospinal fluid and located between the cerebellum and medulla.

What is lumbar cistern?

Lumbar cistern The space inside the arachnoid mater is filled with cerebrospinal fluid (CSF). Below the conus medullaris, this space is enlarged. This enlargement is called the lumbar cistern and contains CSF, the filum terminale, and the cauda equina.

Where is the pontine cistern?

the pons
The pontine cistern (also known as the prepontine cistern), cisterna pontis is one of the subarachnoid cisterns. It occupies a large space on the ventral aspect of the pons and contains the basilar artery. It is filled with CSF and is contiguous with the subarachnoid cavity of the spinal cord.

Which cistern contains the pineal gland?

The pineal gland is a unique midline organ located posterior to the third ventricle in the quadrigeminal cistern. It is surrounded by the splenium of the corpus callosum above, the thalami laterally, and the quadrigeminal plate and vermis below, together delineating the pineal region.

What is the difference between cisterns and ventricles?

Cisterns: The cisterns are not ventricles but rather outpouchings of the subarachnoid space. When evaluating a CT brain the following, certain cisterns have clinical relevance for potential herniation syndromes, layering of subarachnoid blood, and/or the significant structures that run through them.
