The structure contained in the epidural space in the image is fat.
The epidural space is the area between the dura mater (membrane) and the vertebral wall, which contains fat and small blood vessels. The space lies just outside the Dural sac that surrounds the nerve root and is filled with cerebrospinal fluid.
The epidural space contains fat, veins, arteries, spinal nerve roots, and lymphatics. Fat in the epidural space helps absorb shock, which protects other contents in the area, as well as the dura. The dura is the outermost layer of covering, called the meninges, that surrounds the spinal cord. The actual size of the epidural space varies greatly. The distance from the skin to the epidural space in a normal adult usually ranges from 3 to 5 cm.
