Hepatopulmonary metastases from papillary thyroid microcarcinoma: A case report

Figure 1 Positron emission tomography/magnetic resonance imaging images. A: High concentration iodine uptake in the left lobe of the thyroid (arrow); B: Plain computer tomography scan showing the lesions in the left lobe of the thyroid have low-density nodular changes (arrow) involving the thyroid capsule; C: Positron emission tomography (PET)/magnetic resonance imaging (MRI) images showing multiple diffuse nodules in the lung (arrow); D: PET-MRI showing a high concentration of iodide uptake in the liver metastases (arrow).

Figure 2 Chest computer tomography. A-B: Multiple nodules in both lungs suggest metastasis (arrow).

Figure 3 Liver metastasis. A: Abdominal ultrasound showing mixed medium echo nodules near the hepatic capsule in the right lobe of the liver, suggesting metastasis; B-D: Liver magnetic resonance imaging showing multiple liver metastases (arrow).

Figure 4 Whole-body bone imaging and organ tomography. A: Tibial computer tomography; B-D: Radionuclide imaging; C: Radionuclide color imaging.

Figure 5 Postoperative pathology in the left thyroid. A: Liquid-based cytology of fine-needle aspiration; B: Smear staining of fine-needle puncture. C: HE staining.

Figure 6 Immunohistochemical staining. A: CK-19 staining; B: Gal-3 staining; C: TTF-1 staining; D: Ki-67 staining.
