Anatomical Study of Arachnoid Granulation in Superior Sagittal Sinus Correlated to Growth Patterns of Meningiomas [PDF]

Frontiers in Oncology, 2022
Meningiomas in the parasagittal region were formed by arachnoidal cells disseminated among arachnoid granulations. The purpose of this study was to characterize the morphology of chordae willisii, and AGs found in the superior sagittal sinus.

Dural arachnoid granulations and “giant” arachnoid granulations [PDF]

Surgical and Radiologic Anatomy, 2008
Although arachnoid granulations (AGs) were already described by Antonio Pacchioni more than 300 years ago, two issues draw particular attention: first, the radiological features and differential diagnosis of the so-called giant AGs (GAGs) and second, their possible association with various disease processes. In order to evaluate the frequency, size and

Giant arachnoid granulation mimicking dural sinus thrombosis [PDF]

İstanbul Kuzey Klinikleri, 2017
Arachnoid granulations are composed of dense collageneous connective that include clusters of arachnoid cells. They tend to invaginated into the dural sinuses through which cerebrospinal fluid enters the venous system.

Brain Herniation into Giant Arachnoid Granulation: An Unusual Case [PDF]

Case Reports in Radiology, 2017
Arachnoid granulations are structures filled with cerebrospinal fluid (CSF) that extend into the venous sinuses through openings in the dura mater and allow the drainage of CSF from subarachnoid space into venous system. Usually they are asymptomatic but

The Effect of Transverse Sinus Stenosis Caused by Arachnoid Granulation on Patients with Venous Pulsatile Tinnitus: A Multiphysics Interaction Simulation Investigation [PDF]

Bioengineering
This study aimed to investigate the effect of the transverse sinus (TS) stenosis (TSS) position caused by arachnoid granulation on patients with venous pulsatile tinnitus (VPT) and to further identify the types of TSS that are of therapeutic significance

Intravenous arachnoid granulation hypertrophy in patients with Parkinson disease [PDF]

npj Parkinson's Disease
Intravenous arachnoid granulations (AGs) are protrusions of the arachnoid membrane into the venous lumen and function as contributors to the cerebrospinal fluid (CSF) flow circuit.

Giant Arachnoid Granulation Associated with Anomalous Draining Vein: A Case Report. [PDF]

Cureus, 2017
Giant arachnoid granulations (AG) can mimic intracranial lesions. Knowledge of these structures can help avoid misdiagnosis when interpreting imaging. Here, we report a child who presented with a mass within the superior sagittal sinus and an anomalous ...
