It is not normal for a thyroid to show heterogeneity. Langer JE, Khan A, Nisenbaum HL, Baloch ZW, Horii SC, Coleman BG, Mandel SJ: Sonographic appearance of focal thyroiditis. HJM was involved in manuscript drafting and revision. (a) Transverse and (b) longitudinal US showed a 6-mm irregular, taller than wide nodule (arrows) with homogenous echogenicity of the underlying thyroid gland in the right thyroid gland. Underlying heterogeneous echogenicity might make it difficult to differentiate between benign and malignant nodules on US. Multinodular goiters do increase your chance of developing thyroid cancer, but they can be treated with medication, radioactive iodine, or surgery depending on the type, if necessary. Ultraschall Med. WebHypoechogenicity was revealed by comparison of thyroid parenchyma with the echo distribution of surrounding neck muscles.

Among cases with benign cytology, lymphocytic thyroiditis was further diagnosed when the cytological specimen met the following criteria: the specimen showed grouped, monolayer sheets or scattered follicular and Hurthle cells with scattered lymphocytes; the colloid was scanty; and the follicular cells showed nuclear atypia with nuclear enlargement and clearing in the absence of nuclear grooves or inclusions [14]. Blood tests can measure the levels of thyroid stimulating hormone and thyroxine, which can indicate if a person has hypothyroidism or hyperthyroidism (overactive thyroid). They also occur more often in people who live in countries in which food isnt fortified with iodine.

When the thyroid nodules showed no suspicious malignant features, they were classified as negative US. Cancer Epidemiol Biomarkers Prev. First, some of the lesions that had undergone US-FNA only once were also included and considered benign or malignant. 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.

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. Besides these considerations, there are no published reports on this topic: Does underlying thyroid parenchyma echogenicity affect the analysis of a thyroid nodule? Its possible to have thyromegaly and not even know it. The majority of poorly defined thyroid nodules represent focal regions of hyperplasia and are benign (Figure 2B). If the nodule is overproducing thyroid hormones and causing hyperthyroidism, one option is to take synthetic thyroid hormones. 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. The diagnostic performance of US assessments in the diagnosis of thyroid malignancy according to the underlying parenchymal echogenicity was compared using a logistic regression with the GEE (generalized estimating equation) method. 10.1089/thy.2012.0205.
