Doctors may also recommend surgery for people with noncancerous thyroid nodules that are causing symptoms such as vocal changes and swallowing or breathing difficulties. If a pregnant women with thyromegaly has an overactive thyroid, shell likely be treated with medications like propylthiouracil or methimazole. Doctors typically evaluate thyroid nodules using ultrasound scans. 10.1001/archsurg.1955.01270080137023. According to the American Thyroid Association (ATA), about 5% of thyroid nodules develop into thyroid cancer. Heterogeneous echogenicity of the thyroid gland significantly lowers the specificity, PPV, and accuracy of US in the differentiation of thyroid nodules. Among the 1,449 nodules, 325 (22.4%) were malignant and 1,124 (77.6%) were benign (Figure1). If a thyroid nodule isn't cancerous, treatment options include: Watchful Even though the majority of thyroid nodules are benign and cause no other symptoms, its still important to have the nodule evaluated in the small chance that its cancer. 8600 Rockville Pike Thyromegaly during pregnancy can lead to complications, such as premature birth and low birth weight. eCollection 2021.

Characteristic US features of HT consist of numerous tiny hypoechoic nodulations or diffuse homogeneous hypoechogenicity with echogenic fibrous bands [14]. If your thyroid is found to be enlarged, your doctor will want to determine the underlying cause. Serum thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb) and TSH-binding inhibitory immunoglobulins (TBII) levels were measured by radioimmunoassay (Brahms, Hennigsdorf/Berlin, Germany). The existence of TPOAb and/or TgAb was defined by a serum concentration of the relevant thyroid autoantibody>60IU/L.

The US feature of focal lymphocytic thyroditis is variable; they can present either as hyperechoic nodules with ill-defined margins, ill-defined hypoechoic nodules, or solid hypoechoic nodules with well-defined margins [6, 11, 14, 35]. Ultrasound Med Biol. One lobe is on upper limits of normal but its normal The majority of poorly defined thyroid nodules represent focal regions of hyperplasia and are benign (Figure 2B). Thyroid. 2004, 37: 337-340. 1991;72:209213. J Ultrasound Med. This study investigated the influence of underlying thyroid echogenicity on the diagnosis of thyroid malignancies. Enewold L, Zhu K, Ron E, Marrogi AJ, Stojadinovic A, Peoples GE, Devesa SS: Rising thyroid cancer incidence in the United States by demographic and tumor characteristics, 19802005. Theyre common, almost always noncancerous (benign) and usually don't cause symptoms. The prognosis for noncancerous (benign) thyroid nodules is great. In this article, we explore what hypoechoic nodules are and whether there is a risk of cancer. We do not endorse non-Cleveland Clinic products or services. Terms and Conditions, On the other hand, thyroid cancer is very rare in central Europe and comprises only a 3/100,000 incidence rate with high incidence of benign nodules [33]. The margins of nodules with lymphocytic thyroiditis were microlobulated or irregular in 8 nodules with underlying homogeneous thyroid echogenicity and 16 nodules with underlying heterogeneous thyroid echogenicity. Graves disease is an autoimmune disease. 2020 Nov;58(6):1041-1057. doi: 10.1016/j.rcl.2020.07.003. Correspondence to Thyroid glands with heterogeneous echogenicity showed significantly lower specificity, PPV, and accuracy compared to thyroid glands with homogeneous echogenicity, 76.3% to 83.7%, 48.7% to 60.9%, and 77.6% to 84.4%, respectively (P=0.009, 0.02 and 0.005, respectively). eCollection 2021.

A TBII exceeding 10% was considered positive. We considered P-values less than 0.05 statistically significant. FOIA 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). This study reveals that the underlying heterogeneous echogenicity of the background thyroid gland influences differentiation between benign and malignant thyroid nodules on US. Thyroid glands with heterogeneous echogenicity showed significantly lower specificity, PPV, and accuracy compared to thyroid glands with homogeneous echogenicity, 76.3% to 83.7%, 48.7% to 60.9%, and 77.6% to 84.4%, respectively (P=0.009, 0.02 and 0.005, respectively). The doctor may use ultrasound scanning to help guide the needle. The suspicious for papillary carcinoma cytological result was designated when the specimen exhibited cytological atypia (nuclei are crowded and overlapping, enlarged, and pleomorphic) but showed insufficient cellularity for definite diagnosis of papillary carcinoma [17].

We also analyzed each US feature of 1399 nodules according to underlying thyroid gland echogenicity while excluding nodules which were diagnosed with lymphocytic thyroiditis to eliminate the lymphocytic thyroiditis effect on US diagnostic performance (Table4). 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. 2021 Mar 16;11:614172. doi: 10.3389/fonc.2021.614172.

MEASUREMENTS OF THYROID GLAND: Heterogeneous echogenicity of the thyroid gland has been associated with diffuse thyroid disease (DTD) including Hashimoto thyroiditis (HT) and Graves disease [14]. In rare cases, a nodule on the thyroid can be cancerous. Heterogeneity means the the texture of the thyroid gland isnt uniform and smooth as seen with a healthy thyroid gland. This texture is spread over the thyroid gland (diffuse). A diffusely heterogeneous thyroid is commonly seen with an autoimmune disease called Hashimotos thyroiditis. CA carotid artery. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Thus, the aim of this study was to evaluate the influence of underlying thyroid echogenicity on diagnosis of thyroid malignancies using US.

This retrospective study was approved by the institutional review board (IRB) and ethics committee of Severance hospital, Seoul, Korea. These include: Even after excluding the nodules which were diagnosed with lymphocytic thyroditis, microlobulated or irregular margins were still more frequently observed in benign thyroid nodules with underlying heterogeneous thyroid echogenicity than in those with underlying homogeneous thyroid echogenicity.
