In neck extension, the dura mater of the cervical spine is slack and thrown into transverse fold.
1,2) They usually originate from the bones of the skull base, at the sphenoethmoidal and spheno-occipital regions, but very rarely can also arise from other intracranial, extraosseous sites like the dura mater, the brain parenchyma or from within the ventricles.
We postulated that the catheters had accidentally entered a fourth space, within the dura mater, which we termed the 'intradural space'.
Adhesions between the Annulus Fibrosus, posterior longitudinal ligament and the ventral dura mater are therefore thought to predispose to this.

Overlying the dura mater is the epidural space, a potential space between the walls of the vertebral canal and the dura matter, which contains blood vessels, fat, nerves, and connective tissue.
