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

Figure 8

(a, b) A 23-year-old female had an oval solid nodule in the thyroid. The nodule had clear margin and abundant peripheral and internal blood flow signals. The nodule was classified as TI-RADS 3 and considered to be a follicular adenoma. (c) The patient received ultrasound-guided microwave ablation. 1 year after treatment, the nodule became smaller. The anterior capsule of the thyroid was interrupted because of thermal ablation. (d) CEUS showed no enhancement in the nodule suggesting complete necrosis.
