If one has had a biopsy positive for vasculitis, which I have, does this mean that the peripheral nerves also have vasculitis and therefore the PN is vasculitic in nature? This was not mentioned in my sural nerve biopsy, although I did have 39% demyelination.

The area where the path showed vasculitis was a thinly cut biopsy of skin on the front of my leg, just below the knee... This biopsy was done several years after the sural nerve biopsy.
