Thyriod i123 scan didnt show nodule

[sue1466]

Okay I feel like i am loosing my mind. I had a utrasound biopsy a ew weeks ago. I was told I have a very large nodule on my right side. Was told most likley it would have to be removed. Went to get a second opinion and he sent me for i123 scan. Okay now I just got back my results stating everything is normal how could this be? My tsh was low in Oct when this started but was told t3 t4 was normal. i have all the symptoms of being hyperactive. I am going to see an endroconologist next week but looking for any answers now. thanks. Do large nodules just disappear? Why didnt this scan show anything?

Large nodules usually do not disappear.  Sometimes ultrasound can be misinterpreted as a nodule but it does not sound like that the case.  If the biopsy was benign this may be a hyper functioning nodule which was low at a TSH while often keeping the T4 and T3 normal (subclinical hyper thyroidism).  The second opinion from an endocrinologist to put all this together seems quite appropriate.
