heterogeneous thyroid without discrete nodulekevin mannix boston herald
On US, a change in the underlying thyroid echotexture involving diffuse thyroid glands can help guide the diagnosis of DTD [1, 25, 26]. 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). Ultrasonographic (US) features of HT have been reported to show a broad spectrum of abnormal features ranging from focal ill-defined hypoechoic areas to diffuse homogeneous hypoechoic regions showing areas of internal echogenic fibrous septa or diffuse heterogeneous hypoechogenicity showing micronodular patterns [14]. For example, if you have obesity, talk to your healthcare provider about attaining a healthy weight for you. Lee YC, Jung AR, Sohn YM, Kim EJ, Eun YG. It is often a sign of inflammation or thyroiditis, notes Dr. Bradford Mitchell for HealthTap. This causes the thyroid to swell.

Choi SH, Kim EK, Kwak JY, Kim MJ, Son EJ: Interobserver and intraobserver variations in ultrasound assessment of thyroid nodules. 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. Validation of Four Thyroid Ultrasound Risk Stratification Systems in Patients with Hashimoto's Thyroiditis; Impact of Changes in the Threshold for Nodule's Shape Criterion. Heterogeneous echogenicity of the thyroid gland significantly lowers the specificity, PPV, and accuracy of US in the differentiation of thyroid nodules.

The mean age of patients included was 50.8years (range, 1595years). Theyre common, almost always noncancerous (benign) and usually don't cause symptoms. Among a total of 1124 nodules diagnosed as benign thyroid nodules, 875 nodules were seen in the background of homogenous thyroid echogenicity and the other 249 nodules were found in that of heterogeneous thyroid echogenicity. Thyroid nodules are very common, and theyre usually not a cause for concern. WebHypoechogenicity was revealed by comparison of thyroid parenchyma with the echo distribution of surrounding neck muscles. Well acknowledged suspicious US features suggesting malignancy in thyroid nodules are microlobulated or irregular margins, microcalcifications, hypoechogenicity, and taller than wide shape [13].
