Causes Of Multinodular Goiter
Hmm: Microcalcifications in a thyroid nodule are from small calcium deposits in the cells. Thyroid cancer can be associated with this finding, however, benign nodules can also have them. A nodule with microcalcifications should have a fine needle aspiration to help diagnose which it is. ...Read moreSee 1 more doctor answer
Define goiter: Hi. Strictly speaking, goiter only refers to an abnormal size and/or shape of the thyroid. Therefore, goiter can be diffuse, multi-nodular, or uni-nodular. Underlying causes can be autoimmunity, neoplasia (benign or malignant), and drugs (e.g., lithium, amiodarone). So, a lot to causes. ...Read more
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
Nodule...: Tumour, cyst, bleeding into any of the avove. ...Read more
Most: Thyroid nodules are benign some however can be cancerous. If you have a lump in your thyroid it should be followed closely by your doctor. Most benign thyroid nodules occur spontaneously without any known cause. As often happens with organs that have a secretory function (ie ovaries)fluid filled inclusions can form and grow. Follow-up with your treating physician. ...Read moreSee 1 more doctor answer
Symptoms?-I can help: Most multi-nodular goiters do not cause symptoms and are discovered on routine physical exam. If the goiter is large enough, patients may have compressive symptoms that can include difficulty breathing (especially when lying flat), food or pills getting "stuck" in the throat, choking sensation, or a fullness in the neck. ...Read more
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
Could be: It is difficult to reliably sonographically differentiate hashimoto thyroiditis from other thyroid pathology. Ultrasound features can be variable depending of the severity and phase of disease. A diffusely enlarged thyroid gland with a heterogeneous echotexture is a common sonographic presentation. ...Read more
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
Depends: Hi. Goiter (abnormal size/shape of thyroid) can occur with hyperthyroidism, hypothyroidism, and euthyroidism. Broadly, goiter results from autoimmunity, benign tumors, or cancers. If you see an endocrinologist, this will be sorted out. You have Dr. Michael McDermott right there at CU School of Med, a great doc. Good luck! ...Read more
Your Dr is the guide: You need to tell us more...Why did you go to your doctor to start with? What has he/she advised you to do?. The cause of pain is unknown. It can be bleeding into a cyst. Cancer cannot be excluded unless you get this thyroid nodule removed surgically. ...Read moreSee 1 more doctor answer
Several things: It could be a colloid cyst - an accumulation of thyroid hormone. It could be a benign adenoma - an area of thyroid gland that is growing slightly differently/faster than the rest of the gland. Most physicians follow benign thyroid nodules to see if they are growing or changing, which may necessitate another biopsy. ...Read more
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
Prominent vessels in lobe of thyroid, nodule on other lobe, hypothyroid, inconclusive fna of nodule?
Thyroid nodule: The thyroid nodule is not likely to be caused by pregnancy. Transient mild hyperthyroidism can sometimes be seen in the first trimester but should resolve as long as it is not an underlying problem that has not been diagnosed. Would suggest repeating labs for thyroid function at 16-18 weeks. Should talk to your doctor. ...Read more
