Abstract: A 51-year-old woman with papillary thyroid cancer had recurrent disease. An unexpected FDG-avid hepatic metastasis was identified. Follow-up contrast-enhanced CT scan showed a hepatic lesion, compatible with malignancy. Histopathologic examination demonstrated metastatic carcinoma, consistent with thyroid primary. Few studies reported liver metastases originating from thyroid cancer on FDG PET. These were medullary thyroid carcinomas (MTC) or poorly differentiated cancers. There are no reports describing liver metastasis from PTC diagnosed by FDG PET/CT.
