The cervicothoracic tomodensitometry (TDM) concluded that there was a heterogeneous hypodense nodule in the posteroinferior pole of the right thyroid lobe (Figure 1).
Photomicrographs of the histopathological examination showing tumor proliferation made of uniform cells arranged in lobules, trabeculae, and clusters that are separated by dense fibrous bands (a). Neoplastic cells are roughly polygonal, with an atypical nucleus, prominent nucleoli, and abundant cytoplasm, and mitotic figures are frequent (b). Vascular and capsular invasions were observed inside the tumor and in the surrounding tissues. The tumor also displays evidence of capsular invasion (c).

The postoperative follow-ups were marked by the persistence of hypercalcemia between 133 and 151 mg/l and serum PTH level values between 2300 and 2884 pg/ml requiring the performance of another cervico-thoraco-abdomino-pelvic scan which objectified a tissue infiltrate concerning exeresis lodge (Figure 3) with a secondary hepatic lesion.
Suspected hepatic segment VIII lesion. The same lesion is in hyposignal T1 and hypersignal T2.

An MRI was requested for a more precise study of the number and location of the liver lesions which revealed a suspicious lesion of segment VIII of the liver (Figure 4).
