Experience with Dorsal Arachnoid Web (DAW) in T-Spine?

I just received MRI results of my thoracic spine, which was conducted in order to place a spinal cord stimulator for chronic pain in my lumbar spine: L5/S1 nerve damage and hyper mobility in my L3 and L4. However, the MRI shows that I have a Dorsal Arachnoid Web (DAW), a rare, acquired, or sometimes congenital condition where a band of thickened tissue in the arachnoid membrane causes dorsal compression of the spinal cord in my t-spine.

Does anyone in this community have any experience with this condition? Much appreciated.
