case_images: A 48-year-old woman presented to an endocrinologist following the incidental detection of a small thyroid nodule. (A) Thyroid ultrasound shows an ACR-TIRADS 5 nodule in the right lobe, measuring 4.8 x 5.6 x 6.4 mm. (B) Elastography reveals the entire lesion in hard blue with a strain ratio of 2.5. (C, D) A necrotic area measuring 7.4 x 6.4 x 11.4 mm is visible, with the surrounding thyroid tissue showing homogeneous echogenicity.

case_images: ACR-TIRADS 5 nodule in the right lobe, measuring 4.8 x 5.6 x 6.4 mm, with no suspicious lymph nodes or evidence of extrathyroidal extension (Fig. 1A) and the whole lesion appeared hard on elastography, with a strain ratio of 2.5 (Fig. 1B). A fine needle aspiration biopsy was performed, yielding a Bethesda VI classification on cytology, indicative of malignancy. At a one-month follow-up, the clinical examination was unremarkable, and ultrasound showed a necrotic area measuring 7.4 x 6.4 x 11.4 mm with homogeneous echogenicity of the thyroid gland (Figs. 1C, 1D).
case_images: (A, B) Six months post-ablation, ultrasound demonstrates heterogeneous echogenicity in the thyroid gland with markedly increased vascularity on Color-Doppler imaging. (C, D) At 12 months post-ablation, ultrasound reveals homogeneous echogenicity of the thyroid gland with no signs of tumor recurrence.

case_images: Ultrasound revealed heterogeneous echogenicity of the thyroid gland with increased blood flow on Color Doppler imaging (Figs. 2A, 2B). Ultrasound revealed no tumor recurrence, with homogeneous echogenicity, reduced blood flow on Color Doppler imaging of the thyroid gland (Figs. 2C, 2D), and blood tests were in normal ranges.
