Figure 8: A 44-year-old female presented with severely raised parathormone with USG features showing bilateral parathyroid adenoma with multiple hypoechoic lesions in thyroid gland. Tc99m sestamibi scan (a) early images show increased tracer uptake in the upper and lower poles of the both lobes of the thyroid gland with normal uptake in the other areas; (b) delayed images show retention of the tracer in upper and lower poles of the both lobes of the thyroid gland with washout from other parts. (c) SPECT/CT localizes area of increased tracer uptake to the posterior part of the upper and lower poles of both lobes of the thyroid
