A subset of arachnoid granulations in humans drain to the venous circulation via intradural lymphatic vascular channels.

Journal of Neurosurgery, 2021
OBJECTIVE The discovery of dural lymphatics has spurred interest in the mechanisms of drainage of interstitial fluid from the CNS, the anatomical components involved in clearance of macromolecules from the brain, mechanisms of entry and exit of immune ...

Dynamic Nature of Arachnoid Granulations During Acute Changes in Intracranial Pressure: A Pilot Study

Journal of Neuroimaging
Arachnoid granulations (AGs) are cerebrospinal fluid drainage structures whose number and size may vary with intracranial pressure (ICP). Although changes in AG size following lumbar puncture have been reported, longitudinal changes in patients with and ...

Study of Arachnoid Granulations and Their Pits in Head Injuries.

American Journal of Forensic Medicine and Pathology
Although arachnoid granulations (AGs) and their pits have been known for over 300 years, they have not been extensively studied regarding the injuries inflicted upon them.

THE ROLE OF CEREBROSPINAL FLUID DYNAMICS IN ARACHNOID GRANULATIONS AND BRAIN HERNIATION: CLINICAL SIGNIFICANCE AND IMPLICATIONS

International journal of scientific research
Background: Arachnoid granulations (AGs) are small projections into the brain's venous sinuses, crucial for cerebrospinal uid (CSF) absorption. Brain herniation into arachnoid granulations (BHAGs) is associated with elevated intracranial pressure ...

Spontaneous Cerebrospinal Fluid Leak Presenting as Middle Ear Effusion Caused by Arachnoid Granulations

Indian Journal of Otology
While middle ear effusion (MEE) is a common ailment in children with Eustachian tube dysfunction, it occurs less frequently in adults. In such cases, a meticulous assessment is essential to discern the underlying cause of MEE.

Tissue damage in herniated brain parenchyma into giant arachnoid granulations: demonstration with high resolution MRI

Acta Radiologica, 2020
Background Brain herniation (BH) into arachnoid granulation has been remarkable in recent years. Purpose To evaluate the damage in herniated parenchyma into the giant arachnoid granulation (GAG) and to investigate the clinical–demographic importance of ...

Arachnoid Granulation Cerebrospinal Fluid Otorrhea

Annals of Otology, Rhinology & Laryngology, 1990
A case report and review of the temporal bone (TB) collection in the Department of Otolaryngology at SUNY Health Science Center in Syracuse demonstrated the occurrence of arachnoid granulations (AGs) in the posterior fossa surface of the TB and their role in cerebrospinal fluid (CSF) otorrhea.
