Objective: The aim of this study was to determine the diagnostic accuracy of incidental FDG-PET/CT uptake in the thyroid in patients with cancers of nonthyroidal origin, in order to reduce the number of thyroidectomies performed on nodules that subsequently proved to be benign.
Material and methods: From January to September 2011 a total of 2510 patients were evaluated at our institution with whole-body FDG-PET. The studies were done for a variety of diagnoses including metastatic work-up for lymphoma, head and neck cancer, and other nonthyroidal malignant nodules. 30 patients were identified with incidental focal or diffuse uptake in thyroid bed. All patients underwent measurement of serum level of thyroid hormones and ultrasonography (US). While the patients with focal uptake underwent fine needle aspiration biopsy, FNAB.
