A, B: Computed tomography findings in the lung. A solid 30 mm mass (arrow) in the middle lobe of the right lung (A) and several 5 mm nodules (arrowheads) (B) can be seen in both lungs. C: Ultrasonographic findings in the thyroid gland. A hypoechoic mass measuring 8.6 × 4.6 mm and showing an indistinct border can be seen in the right lobe of the thyroid gland (arrow). D: 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) findings. Strong FDG uptake is detected in the right lung tumor (arrow) and multiple tumors in the left lung (arrowhead). E: 131-iodine scintigraphy findings after the second radioactive iodine (RAI) treatment. 131-iodine has accumulated in the metastatic tumor in the middle lobe of the right lung
