case_images: Given these clinical signs, an ultrasound of her neck (Figure 1) was first requested.

case_images: The patient underwent a cervical CT scan (Figure 2) for a better characterization of the tumor, which showed a tissular mass posterior to the left thyroid lobe, extending from the vertebral body C6 to D3, oblong, well limited, with regular contours, hypodense homogeneously enhanced after injection of contrast agent, measuring 14 x 11 x 46 mm.
case_images: Parathyroid sestamibi scintigraphy showing a large focus of MIBI-Tc 99m intense uptake on earlier (a) and delayed images (b), extending from the middle and lower 2/3 of the left thyroid gland to the low cervical level, contrasting with a complete thyroid washout at the end of the examination.. MIBI: 99mTc-sestamibi scintigraphy.

case_images: Following surgery, serum calcium and PTH normalized, and the pathological examination of the specimen (Figure 4) was consistent with PTA.
