Technetium sestamibi scintigraphy with "subtraction" method were performed, both showing no signs of pathologically modified parathyroid glands. The preoperative parathyroid scintigraphy images realized by "subtraction" method are presented in Figure 1.

Technetium sestamibi planar scintigraphy with "washout" method combined with SPECT/CT was done, which revealed on early phase inhomogeneous radiotracer uptake in the right thyroid lobe, with increased uptake in the area of projection of the lower third of the right thyroid lobe. The preoperative parathyroid scintigraphy images accomplished with "washout" method are presented in Figure 2 and early images of SPECT/CT scan are presented in Figures 3 and 4.
