It's always horrible to read medical reports when you had no idea there had been findings that hadn't been shared with you. Hopefully you have been able to get in touch with your doctor now to ask about the mention of the MRI.
This is probably no help at all but when my dad had pancreatitis caused by gallstones it was also mentioned in various scan reports before he had his gallbladder removed that he had some 'cysts' but no one at the time thought it was necessary to do anything about them.
I'm sure that if you'd had something sinister for two years you would know about it by now. Definitely don't google in the meantime, and hopefully your doctor will be able to explain and reassure you
