Images of a 62-year-old woman (case 11) with three parathyroid hyperplastic lesions. The early (a) and late (d) planar ^99mTc-sestaMIBI SPECT/CT images, MIP (maximum intensity projection) images of ^99mTc-sestaMIBI SPECT/CT (b), and fusion image (e) cannot present all three lesions clearly because of Hashimoto’s thyroiditis. Although the MIP image of ¹⁸F-FCH PET (c) is unclear due to renal osteopathy, the lesion is visible in the image (arrows). An ¹⁸F-FCH PET/CT fusion image (f) shows homogeneous tracer uptake behind the left lobe of the thyroid gland (arrow)
