A hypoechoic thyroid nodule is a type of thyroid nodule that appears dark on an ultrasound scan and typically indicates a solid mass rather than a fluid-filled cyst. The thyroid nodules in a thyroid gland with heterogeneous echogenicity had a significantly lower specificity, PPV and accuracy compared to those with homogeneous echogenicity. These nodules are usually noncancerous (benign), but they may produce their own thyroid hormone and cause hyperthyroidism. When theres more than one nodule on the thyroid, its called multinodular goiter. In benign thyroid nodules, microlobulated or irregular margins were more frequently seen in thyroid glands with heterogeneous echogenicity than in those with homogenous echogenicity (P<0.001). Our editor completed a hands-on review of their products and reputation. What causes this, and is surgery always necessary? Second, seven radiologists with varied experience performed US examinations and US-FNA, and interobserver variability among the radiologists may exist [34, 37]. A doctor may also discover thyroid nodules during a routine examination or an imagining test of a persons head and neck. Epub 2009 Nov 25. Hashimotos thyroiditis is usually treated with synthetic thyroid hormone replacement such as levothyroxine (Levothroid, Synthroid). The thyroid then swells. There were 3 patients who underwent US-FNAs at 3 nodules, 70 patients who underwent US-FNAs at 2 nodules, and 1300 patients who underwent US-FNAs at 1 nodule. If a doctor suspects that a thyroid nodule is cancerous, they will usually recommend a thyroidectomy, which is a surgical procedure to remove part or all of the thyroid gland. The enlarged area can put pressure on your throat, which can cause the following symptoms: Thyromegaly that occurs as a result of hypothyroidism or hyperthyroidism is associated with a number of symptoms.

US-FNAs were performed using a freehand biopsy technique with a 23-gauge needle attached to a 2-ml disposable plastic syringe. In the underlying heterogeneous echogenicity group, 270 were women and 28 were men while in the underlying homogenous echogenicity group, 856 were female and 219 were male, exhibiting female predominancy in the underlying heterogeneous echogenicity group (P<.001). However, FNAs were sometimes performed on multiple nodules in one patient because of multiple suspicious US features, physicians or patients request. The prognosis for cancerous (malignant) thyroid nodules varies greatly depending on several factors, including: If you have thyroid cancer, your healthcare provider will be able to give you a more accurate prognosis.

The outlook for thyromegaly depends on the underlying cause and the size of the goiter. Background: Benign and malignant nodules can coexist with DTD [5, 6]. Among the 1,373 patients, 1,126 were women (mean age, 50.5years, range, 1595years) and 247 were men (mean age, 52.1years, range, 2580years). In rare cases, nodules can grow big enough to cause the following symptoms: Hyperfunctioning thyroid nodules can lead to overproduction of thyroid hormones, also known as hyperthyroidism. Heterogeneous echogenicity of the thyroid gland is a non-specific finding and is associated with conditions diffusely affecting the thyroid gland. The mean age (52.312.4years) of the patients with underlying heterogeneous echogenicity of the thyroid gland was older than that (50.412years) of the patients with underlying homogeneous thyroid echogenicity (P=0.015). Therefore, caution is required during evaluation of thyroid nodules detected in thyroid parenchyma showing heterogeneous echogenicity. Alexander LF, Patel NJ, Caserta MP, Robbin ML.

Langer JE, Khan A, Nisenbaum HL, Baloch ZW, Horii SC, Coleman BG, Mandel SJ: Sonographic appearance of focal thyroiditis. Heterogeneous echogenicity of the thyroid gland significantly lowers the specificity, PPV, and accuracy of US in the differentiation of thyroid nodules. Heterogeneous echogenicity of the thyroid gland has been associated with diffuse thyroid disease and benign and malignant nodules can coexist with diffuse thyroid disease.

Thyromegaly during pregnancy can lead to complications, such as premature birth and low birth weight. Ultrasonographic features associated with false-negative and false-positive results of extrathyroidal extensions in papillary thyroid microcarcinoma. This causes the thyroid to swell. Less commonly, a doctor may recommend a nuclear thyroid scan. Between June 2009 and August 2009, there were 1,534 consecutive patients with 1,632 thyroid nodules who underwent US-guided fine needle aspiration (US-FNA) on focal thyroid nodules larger than 5mm in our institution (a referral center) in Korea. The nodules that were diagnosed as lymphocytic thyroiditis occurred in 1.5% (13/875) of underlying homogenous thyroid echogenicity, while under heterogeneous thyroid echogenicity 14.9% (37/249) were found to be focal lymphocytic thyroiditis (Figure4).
