What are the chances of NOT having adeno if adeno comes up as a result on an MRI?

So back in Oct I had an pelvic MRI done for a (now very much confirmed) anal fistula. As part of the results of the MRI, it noted “focal thickening of the junctional zone to a maximum of 1.3 cm… that was possibly reflective of adenomyosis”.

I guess my question is how seriously should I take this? I’m having so many other health issues (see anal fistula, along with advanced Hidradenitis Suppurativa) that I really don’t have the mental capacity to deal with another disease. I do have worsening of all my symptoms (HS, bowels movements, pain) during the pre menstrual phase of my cycle. My periods are tolerable and fairly short, I do get cramps but as long as I catch them with pain meds before they go full bore, they don’t affect my daily life. We have attempted to control the pre-menstrual issues with bcp (yaz) to extreme failure.

My doctors are in specialties that don’t experience adenomyosis, so they have only recommended reaching out to a obgyn. But if this is a common result on MRIs, I’ll put this on the back burner.
