Making IIH just IH?

Curious and going down rabbit holes tonight.

I have read lots on here about getting to remission and stents, etc, but has anyone actually had their doctor be able to diagnose their IIH and change it to IH as they found out what actually caused the intracranial hypertension?

Ie has anyone here been found with just a "plumbing problem" where there was compression on their jugular vein which triggered the body to IH? I think it was called Eagle syndrome?? Or similar type mechanical issues?
