5 rows · May 23, · Nontoxic goiter also called euthyroid goiter, is a diffuse (non-toxic diffuse goiter) or.
Simple nontoxic goiter, which may be diffuse or nodular, is noncancerous hypertrophy of the thyroid without hyperthyroidism, hypothyroidism, or inflammation. Except in severe iodine deficiency, thyroid function is normal and patients are asymptomatic except for an obviously enlarged, nontender thyroid.
Diagnosis is clinical and with determination of normal thyroid function. Treatment is directed at the cause, but partial surgical removal may be required for very large goiters.
See also Overview of Thyroid Function. Simple nontoxic goiter, the most common type of thyroid enlargement, is frequently noted at puberty, during pregnancy, and at menopause. The cause at these times is usually unclear. Known causes include. Ingestion of foods that contain substances that inhibit thyroid hormone synthesis goitrogens, eg, cassava, broccoli, cauliflower, cabbage , as may occur in countries in which iodine deficiency is common.
Drugs that can decrease the synthesis of thyroid hormone eg, amiodarone or other iodine-containing compounds, lithium. Iodine deficiency is rare in North America but remains the most common cause of goiter worldwide termed endemic goiter. Compensatory small elevations in thyroid-stimulating hormone TSH occur, preventing hypothyroidism, but the TSH stimulation results in goiter formation. Recurrent cycles of stimulation and involution may result in nontoxic nodular goiters. However, the true etiology of most nontoxic goiters in iodine-sufficient areas is unknown.
The patient may have a history of low iodine intake or overingestion of food goitrogens, but these phenomena are rare in North America. In the early stages, the goiter is typically soft, symmetric, and smooth. Later, multiple nodules and cysts may develop.
In the early stages, thyroidal radioactive iodine uptake may be normal or high with normal thyroid scans. Thyroid function test results are usually normal. Thyroid antibodies are measured to rule out Hashimoto thyroiditis. In endemic goiter, serum TSH may be slightly elevated, and serum T4 may be low-normal or slightly low, but serum T3 is usually normal or slightly elevated.
Thyroid ultrasonography is done to determine whether there are nodules that are suggestive of cancer. In other instances, suppression of the hypothalamic-pituitary axis with thyroid hormone blocks thyroid-stimulating hormone TSH production and hence stimulation of the thyroid.
Moderate doses of L-thyroxine to mcg orally once a day depending on the serum TSH are useful in younger patients to reduce the serum TSH to the low-normal range. L-Thyroxine is contraindicated in older patients with nontoxic nodular goiter, because these goiters rarely shrink and may harbor areas of autonomy so that L-thyroxine therapy can result in hyperthyroidism.
Large goiters occasionally require surgery or iodine to shrink the gland enough to prevent interference with respiration or swallowing or to correct cosmetic problems. Blocking thyroid-stimulating hormone production by giving L-thyroxine is useful in younger patients to halt stimulation of the thyroid and shrink the goiter.
