Diffuse increased uptake on (18)F-Fluorodeoxyglucose Positron Emission Tomography ((18F)FDG PET) is a well-known finding of the lymphocytic thyroiditis. Nevertheless, a pathologic confirmation is needed in cases of a focal (18F)FDG uptake in the thyroid gland. This article reports a rare case of a focal (18F)FDG uptake lesion by PET, which was revealed pathologically to be lymphocytic thyroiditis.
