Figure 7: CT scan of mass lesion [Figure 7, upper panel] measuring 4.3 cm × 3.2 cm in right thyroid bed, encasing and infiltrating the trachea; abutting right carotid sheath (blue arrow); enlarged right paratracheal nodes in superior mediastinum ~ 2.8 cm, enlarged left hilar lymph node measuring 1.6 cm. Enlarged right level II and right level III nodes were also noted. fluorodeoxyglucose-positron emission tomography/computed tomography and Ga-68 DOTATATE positron emission tomography/computed tomography MIP images [Figure 7, lower panel right] with metastases. Axial images of positron emission tomography-computed tomography [Figure 7, lower panel, left] showing low grade fluorodeoxyglucose uptake in the infiltrative right paratracheal soft tissue lesion with high fluorodeoxyglucose uptake in the left para-hilar soft tissue lesion. A low grade fluorodeoxyglucose uptake in the right lung nodule is also seen. There is low grade uptake in all lesions on 68Ga-DOTATATE positron emission tomography/computed tomography
