Abstract
Thyroid incidentalomas are frequently reported on 18F-FDG PET/CT scan. High risk of malignancy is thought to be associated with increased metabolic activity and high standardized uptake value. Likewise, thyroid nodules with focal FDG avidity have a higher potential to be malignant. However, some benign nodules such as follicular and Hurthle cell adenomas can also present with focal hypermetabolic activity. We report a case of a 59-year-old lady diagnosed with gastric carcinoma, who had a hypermetabolic thyroid nodule on FDG PET/CT scan. Despite the complex texture of the nodule and intense focal avidity, the histopathology was consistent with Hurtle cell adenoma.

Summary
Thyroid incidentalomas are frequently reported on 18F-FDG PET/CT scan. High risk of malignancy is thought to be associated with increased metabolic activity and high standardized uptake value. 18F-FDG PET/BT görüntülemede tiroid insidentalomalarına sık rastlanır. Yüksek malignite riski artmış metabolik aktivite ve yüksek standart tutulum değeri ile ilişkilendirilmektedir.
