Fig.1

A middle-aged patient suffered from SHPT. The axial CT (a and c) and SPECT/CT (b and d) images showed two large soft-tissue masses with marked MIBI uptake in the back of the inferior poles of bilateral thyroid lobes (arrows). The axial CT (e) and SPECT/CT (f) images showed two small soft-tissue masses with slight MIBI uptake in the back of the upper poles of bilateral thyroid lobes (arrows). The maximum density projection image (g) only showed two foci in the inferior pole of bilateral thyroid lobes (arrows). Four lesions in the back of the thyroid gland were pathologically confirmed to be parathyroid hyperplasia. In the initial diagnosis, the lower left and right lesions were diagnosed correctly, but the upper left and right lesions were missed. The early and late planar images (h and i) showed MIBI uptake in the inferior pole of left thyroid lobe (arrows). US images (j–m) showed 4 enlarged parathyroid glands in the back of the upper and inferior poles of bilateral thyroid lobes.
