Arachnoid granulation - Wikipedia
Arachnoid granulations (also arachnoid villi, and pacchionian granulations or bodies) are small outpouchings of the arachnoid mater and subarachnoid space into the dural venous sinuses of the brain. The granulations are thought to mediate the draining of cerebrospinal fluid (CSF) from the subarachnoid space into the venous system .
Arachnoid granulation - Radiopaedia.org
2024年7月19日 · Arachnoid granulations, also known as Pacchionian granulations, are projections of the arachnoid membrane (villi) into the dural sinuses that allow CSF to pass from the subarachnoid space into the venous system. They increase in size and number with age and are seen in approximately two-thirds of patients.
Arachnoid granulations Symptoms, Causes, Treatment
Arachnoid granulations, also known as a Pacchionian granulation, are projections of the arachnoid membrane (villi) into the dural sinuses that allow CSF entrance from the subarachnoid space into the venous system.
Giant Arachnoid Granulations: A Systematic Literature Review
Arachnoid granulations (AGs) are macroscopically visible arachnoid tissue outpouchings that protrude into bone, dura, and/or dural venous sinuses (DVSs) [1]. Historically, they have been defined by their juxtaposition and drainage into the superior sagittal sinus (SSS) and other DVSs.
Arachnoid granulations: Anatomy and function - Kenhub
2023年10月30日 · Arachnoid granulations are pockets of arachnoid membrane and subarachnoid space which connect cerebrospinal fluid to venous circulation. They extend from the subarachnoid space through the dura mater to enter the walls of dural venous sinuses and allow for the passage of cerebrospinal fluid.
Arachnoid Granulation - an overview | ScienceDirect Topics
Arachnoid granulations are small outpouchings of the pia-arachnoid that protrude into the venous sinuses or inner table of the skull. They can be found along the high convexities of the skull or skull base and may resemble an epidermoid cyst or metastasis.

2023年6月18日 · Arachnoid granulations, also known as Pacchionian granulations, are projections of the arachnoid membrane (villi) into the dural sinuses that allow CSF to pass from the subarachnoid space into the venous system.
Arachnoid granulations are lymphatic conduits that …
Arachnoid granulations are poorly investigated. We show that they harbor immune cells and communicate with perisinus spaces, suggesting that granulations subserve neuroimmune roles and function as transarachnoidal passageways.

2013年8月5日 · Arachnoid granulations (AGs, Pacchionian bodies or granulations) are protrusions of subarachnoid space into the cerebral venous sinus lumen. On dedicated imaging, AGs may be found in 60–90% of individuals, most commonly adjacent and/or within the superior sagittal, transverse, and straight sinuses.
Case 5 - Arachnoid granulations - Cambridge University Press
2013年3月5日 · An arachnoid granulation typically occurs where a superficial vein drains into the venous sinus, which is thought to induce a focal weakness in the sinus wall. There may be a smooth corticated erosion of the adjacent calvarium.
