case_images: PET/CT at 4 months (a) and 8 months (b) after total thyroidectomy. There is new focal uptake within the posterior right lobe of the liver, measuring a maximum SUV of 5.4, consistent with metastatic disease. This was not evident on the initial PET/CT.

case_images: A positron emission tomography-computed tomography (PET-CT) at 4 months postoperatively was unremarkable (Figure 1(a)). PET scan was repeated and this lesion was fluorodeoxyglucose (FDG) avid (Figure 1(b)), and it was also confirmed with an abdominal MRI (Figure 2(a)).
case_images: Abdominal MRI before microwave ablation shows a rounded lesion in liver segment 6, measuring 2.1 x 2.1 cm, which demonstrates T2 hyperintensity with heterogeneous internal enhancement or restricted diffusion on MRI (a). 2 months after microwave ablation of the liver, there is evidence of postoperative and postmicrowave changes in the liver, with no suspicious enhancement in the ablation bed to suggest definite residual or recurrent tumor, and no new focal liver lesions (b).
