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}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/32/4/E58}, eprint = {https://www.ajnr.org/content/32/4/E58.full.pdf}, journal = {American Journal of Neuroradiology} }
