Contrast-Enhanced Ultrasound: An Effective Method for Noninvasive Diagnosis of Mummified Thyroid Nodules

Figure 9

(a, b) A 55-year-old female had a hypoechoic solid nodule in her thyroid, with a maximum diameter of 6 mm and a hypoechoic halo around the nodule, uneven in thickness. The margin of the nodule was not clear, and no blood flow signal was detected in the nodule. The nodule was classified as TI-RADS 4 and was considered to might be a mummified nodule. (c) CEUS showed that the nodule had uneven low enhancement, unclear margin, and no ring enhancement, which was similar to the enhancement mode of a PTC. (d–f) SonoLiver software was used to analyze the contrast video. According to the analysis results, the nodule was considered to be a PTC. Postoperative pathology confirmed this result.
