The marginal sinus is an intradural venous sinus of the brain.

Anatomy

The marginal sinus surrounds the Foramen magnum. The marginal sinus communicates with the vertebral venous plexus[^2] and drains venous blood from the basilar plexus, conveying it via the Sinus occipitalisConfluens sinuumCanalis nervi hypoglossiSinus sigmoideus

Anatomical measurements

In a cadaveric study (n=15), the vertical height of the marginal sinus ranged from 7 to 15 mm (mean 10 mm) and was located at the lateral margin or near the region where the Accessory nerve passes to the Jugular foramen[^1]
