I have pulsatille tinnitus of fairly recent onset (last 6 months). So I was prescribed an MRI of the brain with and without contrast to rule out intercranial hypertension, brain tumor, and/or venous or arterial malformations. MRI was negative, so the ENT specialist concluded my tinnitus is either idiopathic or imagined.
I have many other ME symptoms that got worse in recent years and then exponentially worse after a late summer flu in 2018, so I assume that the ME I have had for 20 years is progressing. Have had about $120K worth of a medical workup recently, including David Systrom’s iCPET and a skin biopsy for small fiber polyneuropathy.
I can now say to former coworkers that I have cardiac preload failure (negative right atrial pressure at rest that fell further into negative terrain during the CPET), impaired oxygen extraction consistent with mitochondrial dysfunction and/or microscopic left-right shunt, and small fiber polyneuropathy. Those sound more serious than ME/CFS, but - mestinon aside (which isn’t working so far) - have no proven treatments.
But the short answer to your question is “yes”, though I think a spinal tap is usually needed to make a definitive diagnosis of IIH.
