Definition and location of the falx cerebri. The brain is bathed in fluid during life. The name of this substance is cerebrospinal fluid (CSF). It provides the brain with nutrients, allows for solute exchange, and provides basic mechanical and functional support to the organ. The subarachnoid cisterns, or basal cisterns , are compartments within the subarachnoid space where the pia mater and arachnoid membrane are not in close approximation and cerebrospinal fluid (CSF) forms pools or cisterns (Latin: "box"). As they are interconnected, their patency is essential for CSF circulation.

The subarachnoid cisterns are spaces formed by openings in the subarachnoid space, an anatomic space in the meninges of the brain. [1] The space is situated between the two meninges, the arachnoid mater and the pia mater. These cisterns are filled with cerebrospinal fluid (CSF). [1] Structure CT Brain Anatomy CSF spaces Key points The CSF spaces comprise the sulci, fissures, basal cisterns and ventricles An appreciation of the normal appearances of the CSF spaces is required to allow assessment of brain volume The brain is surrounded by cerebrospinal fluid ( CSF) within the sulci, fissures and basal cisterns.

The subarachnoid cisterns are clinically and surgically significant enlarged cerebrospinal fluid (CSF)-filled pockets of the subarachnoid space that transmit important neurovascular structures including cranial nerves and intracranial vessels.

The subarachnoid space is described as a cistern at points where spaces exist between it and the underlying pia mater. At different points around the brain, the cisterns are described with respect to adjacent anatomical landmarks. Notable cisterns include the: suprasellar or chiasmatic cistern; interpeduncular cistern; prepontine cistern The interpeduncular cistern is located at the base of the brain at the junction where the arachnoid mater stretches between the two temporal lobes, occupying the interpeduncular fossa. Located within this cistern is the optic chiasm as well as some important neurovascular structures which include:. The epidural space in the skull is a potential space, while it is actually present in the spinal cord. The subarachnoid space consists of the cerebrospinal fluid (CSF), major blood vessels, and cisterns. The cisterns are enlarged pockets of CSF created due to the separation of the arachnoid mater from the pia mater based on the anatomy of the. Ambient cistern (Figure 6): Located in the lateral aspect of the brain stem. This cistern has a particular surgical importance as it has both supratentorial and infratentorial extensions. Divided by the superior cerebellar membrane, the superior compartment or posterior cerebral ambient cistern houses the posterior cerebral artery, medial and.
Cisterns of brain and its contents along with its classification and
The interpeduncular cistern is an unpaired CSF-filled subarachnoid cistern located between the cerebral peduncles. It is partially bounded by the leaves of the Liliequist membrane, one of the arachnoid membranes , which separate it from its direct cranial and caudal relations 1. The anterior circulation of the brain is related to the subarachnoid cisterns of the supratentorial region and the cisternal approach to the supratentorial lesions consists of a compartmental opening of one or more of these cisterns (88, 97, 98, 100, 105-107). Any lesion may grow epiarachnoidally or also within one or more cisterns but, in both.
Subarachnoid cisterns - bathes the brain, between arachnoid mater and pia mater. Here the CSF is reabsorbed back into the circulation. By TeachMeSeries Ltd (2024) Fig 3 - The anatomical positioning of the ventricles of the brain. Production and Reabsorption of Cerebrospinal Fluid. The concept of intracranial surgery in terms of moving from one cistern to another is presented here with particular emphasis on the cisterns in surgical approaches to intracranial vessels and nerves for the treatment of aneurysms, arteriovenous malformations, and for surgery of basal tumors. MeSH terms Brain / blood supply

The prepontine cistern, or simply pontine cistern , is an unpaired CSF-filled subarachnoid cistern located ventral to the pons and dorsal to the clivus. It is bounded by arachnoid membranes which separate it from surrounding cisterns. superiorly the mesencephalic leaf of the membrane of Liliequist, above which is the interpeduncular cistern. Normal Anatomy The ventricular system is located deep within the brain and is filled with cerebrospinal fluid (CSF). The normal appearance of CSF on magnetic resonance images is that of water. This axial MR image shows the choroid plexus within the ventricles, where CSF is produced.
