BACKGROUND: Papillary thyroid carcinoma (PTC) generally has a good prognosis, while liver metastasis from PTC is rare and difficult to diagnose.
CASE PRESENTATION: A 67-year-old woman was diagnosed with PTC and underwent a left hemithyroidectomy 43 years ago. Two years ago, thoracoscopic right middle lobectomy was performed for a lung tumor, and pathology reports confirmed a metastatic lung tumor of PTC. The patient was followed up regularly with computed tomography, and a liver tumor measuring 16 mm was found in the lateral segment of the liver. Fluorodeoxyglucose positron emission tomography (FDG-PET) was negative for liver tumor. However, FDG uptake was observed at the nodule outside the right lobe of the thyroid gland, suggesting metastasis to the right supraclavicular lymph node. Laparoscopic partial S2 hepatectomy was performed without complications. The final diagnosis was metastatic liver tumor from PTC, and the surgical margins were free of tumor. Postoperatively, the patient underwent complementary thyroidectomy and right supraclavicular lymph node dissection, followed by I-131 ablation. The final diagnosis was PTC of 7 mm and 4 mm and lymph node metastasis of 9 mm. The patient is currently doing well and has had no recurrence 1 year after surgery.
CONCLUSIONS: This case demonstrates that liver metastases from PTC may be found after long-term follow-up, and liver resection might be the most appropriate treatment.
