case_images: An SVS PTH was performed, which indicated that the lesion was in the area of the left brachiocephalic vein (Fig. 2). A third operation was necessary, and a 4DCT of the neck was performed which revealed 2 parathyroid tissue lesions, one at the left lower neck near the left strap muscle just superomedial to the left internal jugular-brachiocephalic vein, and the other superomedial to the first (Fig. 2).
