Can size of thyroid multinodular goiter be reduced?

Can size of thyroid multinodular goiter be reduced?

Maybe: If you treat with levothyroxine, lowering the tsh, the goiter may shrink. But often it does not, at least not much. There is also a risk of inducing hyperthyroidism. If there is a cyst, aspiration of the cyst may shrink the gland, but the fluid in the cyst often comes back. If the goiter is big and compressing airway or esophagus, surgery may be needed. ...Read more

Is the risk of thyroid carcinoma increased with diagnosis of hashimoto thyroiditis when multiple thyroid adenomas are present. Tyab 2470?

Is the risk of thyroid carcinoma increased with diagnosis of hashimoto thyroiditis when multiple thyroid adenomas are present. Tyab 2470?

Not if they function: If the adenomas are "cold" or do not function, then they are likely to be malignant. They do not show up on radionuclide scan because they do not function. Otherwise they are unlikely to be malignant. However, since you have many of them, you likely need and should get further workup, like aspiration biopsy, etc., along with treatment for your hashimoto's. ...Read more

What is the significance of radioactive iodine scan in various throid diseases like myxedema, hashimoto's thyroiditis and graves disease?

What is the significance of radioactive iodine scan in various throid diseases like myxedema, hashimoto's thyroiditis and graves disease?

Hot vs. cold nodule: Iodine uptake by thyroid tissue depends on functioning cells. The most common use for thyroid scan is to assess if a nodule is functional or not. A functional/hot nodule may cause hyperthyroidism but is not likely to be malignant. See this site for more info. http://www.nlm.nih.gov/medlineplus/ency/article/003829.htm. ...Read more

Most physicians follow benign thyroid nodules to see if they are growing or changing, which may necessitate another biopsy. ...Read more

What can be cause of solitary nodule in hashimoto thyroiditis patient?

Hashimoto's nodule: Hashimotos thyroiditis involves inflammation of the thyroid. Often there can be patches of inflammation, and inflammation then leads to scarring (fibrosis). This scarring creates the appearance of nodules. The likelihood of cancer in these nodules is very low, and frequently these "nodules" do not require biopsy. ...Read more

Would suggest repeating labs for thyroid function at 16-18 weeks. Should talk to your doctor. ...Read more
