A 65-year-old woman presented with a dry cough and multiple various sized nodules in both lungs on chest X-ray. A CT scan showed a 9.5 cm sized hypervascular mass in the liver and a 5.5 cm sized intraabdominal mass. A percutaneous needle biopsy of one of the lung nodules revealed a metastatic follicular thyroid carcinoma. Therefore, thyroid ultrasonography was performed, which revealed a 1 cm sized nodule in the right thyroid lobe. Cytology, obtained by ultrasonography guided fine needle aspiration, revealed a follicular neoplasm. The tumor cells were weakly positive on galectin-3 immunostaining, which favored a follicular carcinoma. An ultrasonography guided biopsy of the liver and EUS (endoscopic ultrasonography)-guided biopsy of the intraabdominal mass revealed a metastatic follicular thyroid carcinoma in the liver and peritoneum. We report a very rare case of a follicular thyroid microcarcinoma, with multiple metastases to the lung, liver and peritoneum.
Key Words: Follicular thyroid carcinoma, Intra-abdominal metastasis, Lung metastasis
