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

Figure 6

(a, b) A 33-year-old male was found to have a solid nodule with very low echo near to the front capsule of the thyroid. The nodule had irregular margin and a taller-than-wide shape. The discontinuity of anterior capsule indicated extrathyroidal invasion, and no blood flow signal was detected in the nodule. The nodule was classified as TI-RADS 5. (c) CEUS showed that the whole nodule had uneven low enhancement and unclear margin, but had no ring enhancement. (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.
