| nontoxic goiter | Goiter not accompanied by hyperthyroidism. (05 Mar 2000) |
|---|---|
| diffuse nontoxic goitre | A common cause of hyperthyroidism thought to be caused by an underlying autoimmune mechanism. (27 Sep 1997) |
| goiter, diffuse toxic | Graves' disease, the most common cause of hyperthroidism, too much thyroid hormone. (12 Dec 1998) |
| diffuse goiter | Goiter in which the morbid process involves the whole gland, as opposed to nodular goiter or thyroid adenoma. (05 Mar 2000) |
| nontoxic goitre | <endocrinology> An enlargement of the thyroid gland that is usually visible as a swelling in the anterior portion of the neck. Simple goitre occurs when the thyroid gland is unable to meet the demands of the body (for example iodine deficiency). The thyroid gland compensates by enlarging. Some foods such as cabbage, soybeans, peanuts, peaches, radishes and spinach contain substances that decrease thyroid production. Some medications such as lithium, cobalt and phenylbutazone can also decrease thyroid hormone production. (13 Nov 1997) |
| aberrant goiter | Enlargement of a supernumerary thyroid gland. Synonym: struma aberrata. (05 Mar 2000) |
| acute goiter | A goiter that develops very rapidly. (05 Mar 2000) |
| adenomatous goiter | An enlargement of the thyroid gland due to the growth of one or more encapsulated adenomas or multiple nonencapsulated colloid nodules within its substance. (05 Mar 2000) |
| Basedow's goiter | Colloid goiter which becomes hyperfunctional after the ingestion of excess iodine, the Jod-Basedow phenomenon. (05 Mar 2000) |
| cabbage goiter | Goiter due to ingestion of cabbage or other goitrogenic foodstuff. (05 Mar 2000) |
| parenchymatous goiter | A form of goiter in which there is a great increase in the follicles with proliferation of the epithelium. Synonym: follicular goiter. (05 Mar 2000) |
| goiter | Enlargement of the thyroid gland. A goiter is not cancerous. A goiter can be associated with normal, elevated (hyperthyroidism) or decreased (hypothyroidism) thyroid hormone levels in the blood. (12 Dec 1998) |
| goiter, endemic | Enlargement of the thyroid gland in a significantly large fraction of a population group, generally considered to be due to insufficient iodine in the diet. (12 Dec 1998) |
| goiter, iodide | Just as too little iodine can cause thyroid disease, so may prolonged intake of too much iodine also lead to the development of goiter (swelling of the thyroid gland) and hypothyroidism (abnormally low thyroid activity). Certain foods and medications contain large amounts of iodine. Examples include seaweed; iodine-rich expectorants (such as SSKI and Lugol's solution) used in the treatment of cough, asthma, chronic pulmonary disease; and amiodarone (Cardorone), an iodine-rich medication used in the control of abnormal heart rhythms (cardiac arrhythmias).

| goiter, nodular | An enlarged thyroid gland containing circumscribed nodules within its substance. (12 Dec 1998) |
