All tests have come back great!!!!The mass on my Thymus appears to be part of the Thymus itself turning into fatty tissue (which is what it's supposed to do:). The results weren't actually inconclusive, the nurse gave me the wrong answer. the doc just wanted to see me to go over ALL the test results from the last couple months. I have to get another MRI in about 6 months, just as a followup, but all looks good!!!!!
We're going to Ocean City this weekend, so I'll come back with plenty of pics:)
