Hi Gray Wolf,

Welcome to NeuroTalk.

I'm sorry you've received no answers as yet.

I can't really help you with your MRI results, but regarding the Perineural Cyst, I would suggest perhaps posting over on the

Tarlov Cyst Forum

Also, there is a post in the 'Sticky' threads above that may be helpful in understanding the terminology used in your results.
