I don’t think I will be of much help here but still wanted to respond. I had a neck para. I never had an MRI, only a CT scan and ultrasound. I never did a “wait and see” as surgery was recommended right away. Has this been discussed for you? A friend of mine had a glomus jugular and it was treated with Cyberknife. If you are on Facebook, a great resource is a page called Pheochromocytoma and Paraganglioma Support Group. There is a lot of knowledge there!
