Detection of Solitary Axillary Lymph Node Metastases from Hurthle Cell Carcinoma of the Thyroid on F-18-FDG PET/CT

摘要

Thyroid carcinoma is the most common neoplasm of endocrine malignancies. Differentiated thyroid carcinoma (DTC) constitutes 90 of the thyroid carcinomas, rest being medullary thyroid carcinoma (MTC), and anaplastic thyroid carcinoma (ATC). Distant metastases occur in up to 10 of patients with DTC. Metastases to axillary lymph nodes (ALN) are very rare. As per literature, only 25 cases have been reported. We report an unusual case of 47-year-old male with Hurthle cell carcinoma of the thyroid presenting with a solitary axillary lymph node metastasis 17years after thyroidectomy, along with review of literature.
