My 15 yr old son recently had an MRI & MRV done on both legs and pelvis area. There were 7 tests done and it took a total of 4 hours to complete them. The reasons for the tests were because he has a port wine stain on one leg and that leg has grown larger (3cm in width) than the other. I noticed it about 2 years ago (around puberty) but it has been brushed off by Doctors until recently. They originally thought it was a hemangioma (spelling?) but the recent tests show that it is not that or any type of vascular malformation they thought it was. They said it was only on the skin level (good news to us!!). But the test report reads in many places that there is something abnormal with the bone marrow. His primary care Doctor ran blood work today and she just called to say that what she has gotten back looks normal. She is pretty confused herself and is now sending a referral for us to go see a hematologist. My son is healthy and doesn't have pain or anything out of the ordinary. He plays HS football and works out daily with no problems ..well he has injured himself a few times lately. Over use issues & pain with his wrists mainly. The only other thing is he has had a chronic sinus infection or sinus issues for the last two years. Last year they removed his tonsils and adenoids (that took away the snoring issues) but he still can't seem to fully breathe through his nose...ever. He is constantly clogged up but we just brush that off at this point after taking so many types of meds and it always comes right back.
My main question is....what would cause the bone marrow to show problems? His bloodwork seemed fine. I don't know if I am worrying too much or I should really be concerned. This was only looked into recently because we finally got a referral to check into his leg for the port wine stain (that has been there all his life!).
