MRI Scan, Need Help Understanding What This All Means?

I had an MRI scan done with the following outcome:

There is a venous angioma/development venous anomaly in the peripheral portion of the right cerebellar hemisphere.
This is draining into the adjacent transverse sinus.
There is a prominent arachnoid granulation within the transverse sinus at the site.

To me it does not sound good, and might be a logical explanation for my pulsatile tinnitus , or is this indeed nothing as mentioned by the specialist?

 

Karen, U R amazing. Where would we be without you?

So glad you have remained part of the TT community all this time. Blessings.
