Hello,
Thank you for asking. I read your concerns carefully.
As you are diagnosed with
hyperthyroidism and the
ultrasound shows only a nodule, without other problems, it means that this nodule is responsible for the overproduction of the thyroid hormones and is called hot nodule.
To confirm that it is a hot nodule (or toxic
adenoma), scintiscan is helpful.
So the next step will be the scintiscan.
Hot nodules has a very very low risk of malignancy and usually
biopsy is not performed for them.
Anyway, after some months of treatment with tablets to stabilize the
hormonal level, you will need a definite treatment for the nodule in order to prevent further episodes of hyperthyroidism.
Hope the information is helpful. It will be a pleasure to answer further questions in the future.
Kind regards,
Dr.Mirjeta
