The human arachnoid granulation was studied by light microscopy in gapless serial sections after local postmortem perfusion of the subarachnoid space with glutaraldehyde
The largest granulations lie along the superior sagittal sinus, a large venous space running from front to back along the center of the head
Jun 17, 2021 · The arachnoid granulations are the protrusions of the arachnoid mater that pierce the dura mater and protrude into the lumina of the dural venous sinuses
The arachnoid mater covering the brain is referred to as the arachnoidea encephali, and the portion covering the spinal cord as the arachnoidea spinalis
Methods A total of 102 patients with intact dural sinuses underwent
They develop at the base of the skull, the surface of the brain, or on the arachnoid membrane
They most commonly occur in the superior sagittal and transverse sinuses
Arachnoid granulations are most commonly located within the transverse sinuses, superior sagittal sinus, and parasagittal venous lacunae [1]

Headaches have been reported in patients with arachnoid granulations, and imaging findings, as well as clinical presentation can lead to the differential diagnosis of venous sinus thrombosis or IIH
21–23 On imaging, they are multilobulated, exhibit fluid attenuation, and lack complete disruption of the cortex (Fig
