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]
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.
Uninodular goitre: one thyroid nodule; can be either inactive, or active (toxic) – autonomously producing thyroid hormone. Multinodular goitre: multiple nodules; [16] can likewise be inactive or toxic, the latter is called toxic multinodular goitre and associated with hyperthyroidism. These nodules grow up at varying rates and secrete thyroid ...
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
Colloid nodules may be initially identified as an unspecified kind of thyroid nodule. Follow-up examinations typically include an ultrasound if it is unclear whether or not there really is a nodule present. Once the presence of a nodule has been confirmed, the determination of the kind of thyroid nodule is done by fine needle aspiration biopsy. [7]
Laser ablation of thyroid nodules is a minimally invasive procedure indicated to treat benign thyroid lesions [1] such as cold nodules or single nodules within a multinodular goiter. The technique consists in the destruction of the tissue by the insertion therein of optical fibers which convey the light energy, causing a complete and not ...
After long-term heavy strain, levels of thyroid hormones decrease. [2] This is exacerbated by other stressors such as undernutrition and lack of sleep, such as in a military training setting. During endurance exercise, before exhaustion, elevated thyroid hormone levels may happen due to increased expected energy demand (type 2 allostatic load). [2]
Medullary thyroid carcinoma may also produce a thyroid nodule and enlarged cervical lymph nodes. [4] Sites of spread of medullary thyroid carcinoma include local lymph nodes in the neck, lymph nodes in the central portion of the chest (mediastinum), liver, lung, and bone. Spread to other sites such as skin or brain occurs but is uncommon.
