PET scan with FDG from a patient with Hürthle cell thyroid cancer

In this FDG-PET scan from a patient with Hürthle cell thyroid cancer, there is evidence of multiple small foci of increased radiotracer uptake. In the left neck, this focus may represent residual carcinoma in the region of the left thyroid bed or within an adjacent lymph node. In addition, foci are notable in the mediastinum and right lung, likely representing distant metastasis. A prior I-123 whole-body scan demonstrated no abnormal uptake.
