Fig. 1From: Liver metastasis from papillary thyroid carcinoma treated by laparoscopic hepatectomy 43 years after resection of the primary tumor: a case reporta Abdominal contrast-enhanced ultrasonography shows a 16-mm echo-free mass in the lateral segment of the liver, which resulted in a defect in the Kupffer phase (arrow). b Enhanced abdominal computed tomography scan shows a 16-mm marginally enhanced tumor in the lateral segment of the liver (arrow). c Fluorodeoxyglucose positron emission tomography (FDG-PET) is negative for liver tumors. FDG uptake (maximal standardized uptake value = 3.43) is observed at the nodule outside the right lobe of the thyroid gland (arrow)Back to article page
