What are 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.
Do humans have cisterns?
In the human body, subarachnoid cisterns of central nervous system are the best-known cisterns, despite the presence of the cisterna chyli and Golgi body.
What does the Quadrigeminal cistern do?

What do cisterns look like?
‘ Cisterns are generally circular structures made of brick or wood. Ranging from 6 to 10 feet in diameter and 7 to 12 feet deep, some were built and then lowered into the ground, while others were constructed in the ground itself.

Where is the superior 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 does CSF appear on CT scan?
CSF is of lower density than the grey or white matter of the brain, and therefore appears darker on CT images.
Can CT Miss CSF leak?
RESULTS: High-resolution CT showed bone defects in 30 of 42 patients (71%) with CSF leak. High-resolution, radionuclide cisternography and CT cisternography did not show bone defects or CSF leak for 12 patients (29%) who had clinical evidence of CSF leak.
Are cisterns still used?
However, modern cisterns still serve important purposes in communities around the world. Even if wells or rivers supply plenty of drinking water for the residents, many areas require cisterns to support agriculture, manufacturing facilities, and industrial projects that demand a lot of fresh water.
How are cisterns filled?
Water enters a cistern from an external source such as rainwater from a rooftop, pumped water from a spring or other supply, or even by delivery by water truck. Water from a cistern is typically pumped out by hand, drained by gravity, or it may be pumped by an electric pump such as a one line jet pump.
What does Quadrigeminal mean?

What is Quadrigeminal cistern lipoma?
Quadrigeminal cistern lipomas make up approximately 25% of intracranial lipomas and are located within the quadrigeminal cistern. They may be associated with hypoplasia of the inferior colliculus or agenesis of the corpus callosum. For a general discussion please refer to the article on intracranial lipomas.
What is Quadrigeminal plate cistern?
The quadrigeminal cistern (also known as superior cistern or cistern of the great cerebral vein) is one of the CSF-filled subarachnoid cisterns.
How long does a cistern last?
Whilst there is no definitive answer to the question of how long a water tank lasts, typically a steel or poly water tank will last a minimum ten years, with poly tanks often lasting over twenty years, and steel tanks upward of thirty.
