Radionuclide parathyroid imaging using technetium sestamibi scan showed slow washout in the right lower thyroid region (Figure 7) but CT scan of the neck with contrast showed moderately enhancing foci inferior to the left and right thyroid lobes and superior to the left thyroid lobe which raised suspicion of parathyroid hyperplasia and warranted exploration of all four parathyroid glands.
