2007;46:547550. Because the underlying heterogeneous echogenicity of the thyroid gland did affect the diagnostic performance of US, we wanted to evaluate which associated US features influenced the analysis of thyroid nodules on US. The diagnostic performance of US had a more superior specificity, PPV and accuracy for diagnosing malignant nodules when thyroid glands showed underlying homogeneous echogenicity rather than heterogeneous echogenicity. It is safe to use during pregnancy and is also a, Medullary thyroid cancer (MTC) is a rare type of thyroid cancer. For this study, we recorded the results by retrospectively reviewing the cytological reports. The thyroid gland secretes two important hormones thyroxine (T4) and triiodothyronine (T3). Although US is a powerful modality for differentiating malignancy from benign focal thyroid nodules [13, 15, 34], some studies have speculated that it might be difficult to detect malignant nodules in patients with HT on US because the heterogeneous hypoechogenicity and micronodulation seen in HT are somewhat similar to features seen in malignant thyroid nodules [2, 12]. J Clin Endocrinol Metab. After US, each US feature was recorded by the radiologists who performed the US on provided result sheets including the underlying echogenicity of the thyroid gland on US. Thyroid. SHP was involved in acquisition of data and revision. Shin D, Kim E, Lee E: Role of ultrasonography in outcome prediction in subclinical hypothyroid patients treated with levothyroxine. What is the relationship between thyromegaly and cancer? However, FNAs were sometimes performed on multiple nodules in one patient because of multiple suspicious US features, physicians or patients request. Doctors are not exactly sure what causes most thyroid nodules. It is related to the formation of the thyroid gland during, A multinodular goiter is an enlarged thyroid gland with several nodules. 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. On the other hand, in malignant thyroid nodules, there were no significant differences in US features according to the underlying echogenicity of the thyroid gland. Rosrio PWS, Bessa B, Valado MMA, Purisch S: Natural history of mild subclinical hypothyroidism: prognostic value of ultrasound. In other word, physicians may have a higher chance to interpret a benign nodule as microlobulated or irregular margin on US in the underlying heterogeneous thyroid echogenicity group than in the underlying homogeneous thyroid echogenicity group, which explains the lower specificity of US in the underlying heterogeneous thyroid echogenicity group. The earliest sign of MTC is typically a painless lump in the neck. Thyroiditis can be caused by: Inflammation can make the thyroid hormone leak out into the bloodstream and the thyroid gland to swell. It is not intended to be and should not be interpreted as medical advice or a diagnosis of any health or fitness problem, condition or disease; or a recommendation for a specific test, doctor, care provider, procedure, treatment plan, product, or course of action. WebA poorly defined margin that is not infiltrative, is often used to describe a nodule that appears to merge into the surrounding thyroid without discrete borders. Blank W, Braun B: Sonography of the thyroid--Part 1. Heterogeneous echogenicity of the thyroid gland has been associated with diffuse thyroid disease and benign and malignant nodules can coexist with diffuse thyroid disease. Heterogeneous echogenicity of the thyroid gland is a non-specific finding and is associated with conditions diffusely affecting the thyroid gland. Its also important to make sure you get enough iodine in your diet. Check for errors and try again. For this reason, you should see your healthcare provider so they can evaluate the nodule to be sure its benign. 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. 2014 May;40(5):884-9. doi: 10.1016/j.ultrasmedbio.2013.11.021. We offer this Site AS IS and without any warranties. It is often a sign of inflammation or thyroiditis, notes Dr. Bradford Mitchell for HealthTap. The prognosis for noncancerous (benign) thyroid nodules is great. -, Singh B, Shaha AR, Trivedi H, Carew JF, Poluri A, Shah JP. AJNR Am J Neuroradiol.

A total of 1,373 patients who underwent US-guided fine needle aspiration of 1,449 thyroid nodules from June 2009 to August 2009 were included. 10/20TSH 9.7/T4Free1.46/ T3Free2.1, swallowing & throat discomfort. Patients with DTD showed significantly more heterogeneous echogenicity (39.8%) of the thyroid parenchyma on US compared with patients without DTD (13.7%, P<0.001). In this study, we evaluated whether the underlying thyroid parenchyma echogenicity affects the analysis of a thyroid nodule and which associated US features impact the analysis of a thyroid nodule on US. You can, however, try to decrease your risk of developing them by managing certain risk factors. Theyre common, almost always noncancerous (benign) and usually don't cause symptoms. Its most often caused by insufficient iodine in the diet, but it can also result from other conditions. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers.

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). I have Toxic Multinodular Goiter with resulting hyperthyroidism and my TSH is very low at .28 I have similar symptoms with the difficulty swallowing and pain in the throat. Each lesion was aspirated at least twice. A doctor may order blood tests to check if the thyroid is functioning normally. A total of 1,373 patients who underwent US-guided fine needle aspiration of 1,449 thyroid nodules from June 2009 to August 2009 were included. If a thyroid nodule isn't cancerous, treatment options include: Watchful Therefore, we do not think that this limitation has a strong influence on the value or result of this study.

Hi recently I was diagonsed with hypothyroidism, and recently went to the E,R, because I had trouble breathing, swallong, and constantly 57 F Thyroid medicine over 20 yrs. 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].

PubMed Therefore, caution is required during evaluation of thyroid nodules detected in thyroid parenchyma showing heterogeneous echogenicity. So, symmetric mild parenchymal heterogeneity could mean that both lobes of the thyroid are showing some heterogeneity, which could be an early indicator of thyroid inflammation, but since it is mild, I wouldn't assume anything is wrong at this point, unless you have had additional tests other than the ultrasound that indicate a thyroid problem. However, if you have several nodules or large nodules, you may be able to see them. Nodules can develop on this gland due to the growth of thyroid tissue or a cyst. Eur Radiol. Google Scholar.
