AB SUMMARY: A 52-year-old man presented with subacute thyroiditis and showed an intensely hypermetabolic thyroid lesion on 18F-FDG PET/CT. The patient also had coexisting chronic lymphocytic thyroiditis. The lesion of subacute thyroiditis revealed an SUVmax of 9.1 g/mL and was ill-defined, heterogeneous, markedly hypoechoic, and hypovascular on US. Biopsy demonstrated histologic findings of subacute thyroiditis, which should be included in the differential diagnosis of an intensely hypermetabolic thyroid lesion on 18F-FDG PET/CT. 18F-FDG PET/CT[18F] fluorodeoxyglucose whole-body positron-emission tomography and CTFDGfluorodeoxyglucoseUSsonographyPDpower DopplerPTCpapillary thyroid carcinomaSUVmaxmaximum standardized uptake valueUS-FNABsonography-guided fine-needle aspiration biopsy
