I know this may be an unlikely scenario, but has anyone had a parathyroid adenoma removed and then to have another parathyroid go bad. Recently, I had an ultrasound and they found three nodules, mind you these were not there just a year ago when I had the parathyroidectomy. The radiologist thought that two of them looked like parathyroid adenomas and the other was a thyroid nodule. They did look different to my untrained eye in that the two was a dense white oval shape and the other was a black hole. They ordered a Sestamibi scan which was done at the local hospital in a small town. It was negative. I've read there's up to (I think) a 22% false negative rate with sestamibi scans and that could be due in part to the inexperience of the technicians who perform them in these smaller hospitals. I should of refused having it done there and had them refer me back to the place where I had the surgery done in St Louis. My throat is often sore and shirt collars feel snug, but I cant really feel any lumps on my throat. Anybody had anything similar to happen, but Id take any suggestions or opinions. Thanks!
