Colloid nodules, also known as adenomatous nodules [1] or colloid nodular goiter [2] are benign, noncancerous enlargement of thyroid tissue. [3] Although they may grow large, and there may be more than one, they are not malignant and they will not spread beyond the thyroid gland. Colloid nodules are the most common kind of thyroid nodule. [4]
Toxic multinodular goiter (TMNG), also known as multinodular toxic goiter (MNTG), is an active multinodular goiter associated with hyperthyroidism.. It is a common cause of hyperthyroidism [2] [3] in which there is excess production of thyroid hormones from functionally autonomous thyroid nodules, which do not require stimulation from thyroid stimulating hormone (TSH).
Nodular goitres are either of one nodule (uninodular) or of multiple nodules (multinodular). [14] Multinodular goiter (MNG) is the most common disorder of the thyroid gland. [15] Growth pattern. Uninodular goitre: one thyroid nodule; can be either inactive, or active (toxic) – autonomously producing thyroid hormone.
Nodular goiter is an enlarged thyroid gland with bumps (nodules) on it. It is associated with both high and low activity of the gland. Toxic multinodular goitre, also known as multinodular toxic goiter (MNTG) Nontoxic nodular goiter
An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic; surgical excision (thyroidectomy), radioiodine therapy, or both may be used. [33]
A goiter is an abnormal thyroid gland proliferation that manifests as multi-nodular, uni-nodular, or non-nodular diffuse glandular enlargement. A goiter is formed of solid matrix, colloid cysts, blood products, calcification, and fibrosis, and this heterogeneity may lead to variable appearances on a CT scan (Figs. 13, 1414 and and15)15).
Nontoxic nodular goiter also known as a nontoxic goiter is an enlarged thyroid without hyperthyroidism. [1] It is often present for years before toxic nodular goiter occurs. [ 1 ] In the United States it is the most common cause of a large thyroid affecting between 3 and 5% of the population.
The absolute indications are a large goiter (especially when compressing the trachea), suspicious nodules or suspected cancer (to pathologically examine the thyroid), and people with ophthalmopathy and additionally if it is the person's preferred method of treatment or if refusing to undergo radioactive iodine treatment.
