“…Though the typical image of SAT in conventional US seems clear, focal distortion and heterogeneity may only be found in some of the patients. In the study by Espinoza et al (13), such an image presented in only eight out of 22 patients with SAT. On the other hand, CAT on conventional US is most often characterized by a diffusely decreased echogenicity, coupled with a varying extent of fibrosis (12).…”

“…Nevertheless, some patients with CAT may complain of thyroid tenderness, which is accompanied by increased temperature and malaise, as well as moderately elevated ESR and CRP, and thus might be misdiagnosed as SAT (12). Though increased antithyroid autoantibodies are indicative of CAT, their presence does not exclude the diagnosis of other types of thyroiditis (13,14). The conventional sonographic image of AT and SAT might be very similar in the first phase of the disease and is characterized by ill-defined regions of heterogeneous decreased echogenicity (15,16).…”

“…Clinically it is silent and typically is not characterized by painful thyroid enlargement or biochemical signs of inflammation. Though elavated antithyroid autoantibodies are highly indicative of CAT, these do not exclude the diagnosis of other types of thyroiditis [2] and correct diagnosis may be difficult in some cases without biopsy. US examination is a noninvasive and commonly used imaging modality for CAT diagnosis [3].…”

Aims: The aim of this study is to assess the applicability of shear wave elastography (SWE) in the diagnosis of chronic autoimmun thyroiditis (CAT) patients. Material and methods: The study group consisted of 50 patients with first-diagnosed CAT and 40 control subjects (CS). In all patients with CAT and CS, sonoelastographic measurements were made in both thyroid lobes. Optimal cut-off values were chosen to maximize the sum of sensitivity and specificity. Positive predictive value (PPV), negative predictive value (NPV), and accuracy values were also calculated. Results: Quantitative elastographic analysis evaluated by SWE in CAT patients (2.56 ± 0.30 m/s) was significantly higher compared with CS (1.63 ± 0.12 m/s) (p<0.001). The optimal cut-off value was 2.42 m/s. SWE had 77% sensitivity, 71% specificity, 92% PPV, 81% NPV, and 87% accuracy for the presence of CAT. Conclusions: Our data indicate that SWE correctly defines the elasticty of thyroid parenchyma, and this technique may assist in the diagnosis and treatment monitoring of CAT.

“…Podostre zapalenie tarczycy (SAT, subacute thyroiditis), nazywane również ziarniniakowym zapaleniem tarczycy lub chorobą de Quervaina, jest samoograniczającym się procesem zapalnym z tendencją do sezonowego i geograficznego występowania [25]. To rzadkie schorzenie zazwyczaj jest spowodowane infekcją wirusową, która indukuje przejściową reakcję autoimmunologiczną [26].…”

“…Subacute thyroiditis (SAT), also called granulomatous or de Quervain thyroiditis, is a self-limiting inflammatory process, with a tendency to a seasonal and geographic occurrence [25]. This uncommon condition is usually caused by a viral infection, which induces a transient autoimmune response [26].…”

Sonoelastography (USE) is a constantly evolving imaging technique used for the noninvasive and objective estimation of tissue stiffness. Several USE methods have been developed, including Quasi-Static or Strain Elastography and Shear Wave Elastography. The utility of USE has been demonstrated in differentiating between malignant and benign thyroid lesions. Recently, USE has been applied in the evaluation of thyroiditis and autoimmune thyroid disease (AITD). Thyroid inflammatory illnesses constitute a diverse group of diseases and may manifest various symptoms. These conditions may share some parallel clinical, biochemical, and ultrasonographic features, which can lead to diagnostic difficulties. USE may be an additional tool, supporting other methods in the diagnosis and treatment monitoring of thyroid diseases, other than thyroid nodular disease. The aim of this article was to analyse and summarise the available literature on the applicability of different elastographic techniques in the diagnosis, differentiation and monitoring of various types of thyroiditis and AITD. Advantages and limitations of this technique are also discussed. StreszczenieSonoelastografia (USE) jest stale rozwijającą się techniką obrazowania stosowaną do nieinwazyjnej i obiektywnej oceny sprężystości tkanki. Jak dotąd opracowano wiele metod USE, które można podzielić na dwie zasadnicze grupy: quasi-statyczną elastografię i elastografię fali poprzecznej (SWE). Wykazano wysoką skuteczność USE w różnicowaniu łagodnych i złośliwych zmian ogniskowych w gruczole tarczowym. Coraz częściej USE znajduje zastosowanie w ocenie zapaleń gruczołu tarczowego, w tym autoimmunologicznej choroby tarczycy (AITD). Zapalne choroby tarczycy stanowią bardzo zróżnicowaną grupę chorób, których wczesne objawy są nieswoiste. Trudności diagnostyczne mogą wynikać zarówno ze wspólnych cech klinicznych, biochemicznych, jak i ultrasonograficznych zapaleń tarczycy. Sonoelastografia może być uznana za dodatkowe narzędzie, wspierające inne stosowane metody w diagnostyce i monitorowaniu leczenia chorób tarczycy innych niż choroba guzkowa tarczycy. Celem niniejszego artykułu była analiza i podsumowanie dostępnej literatury na temat możliwości zastosowania technik elastograficznych w rozpoznawaniu, różnicowaniu i monitorowaniu różnych typów zapalenia gruczołu tarczowego. Przedstawiono zarówno wady, jak i zalety stosowania tej techniki w chorobach tarczycy. (Endokrynol Pol 2014; 65 (6): 520-531)

A Comparison Between Two Imaging Techniques for the Diagnosis of Subacute Thyroiditis (De Quervain Thyroiditis)

Abstract: Low thyroid scan uptake with I-131 at 2 hours (<4%) and 24 hours (<5%), and poor thyroid visualization on TS seem to be more prevalent than focal distortion and heterogeneity in TUS in thyrotoxic phase of SAT.
