Thyroid CA. Contrast-enhanced CT coronal (a) and axial (b) images demonstrate a large mass in the right lower neck associated with an enlarged and heterogeneous right thyroid lobe (asterisk), which is causing leftward shift of the trachea. Enlarged right neck base, mediastinal and right hilar lymph nodes (arrows) are noted. Biopsy of these lesions confirmed the presence of metastatic thyroid cancer. c Coronal FDG-PET/CT shows avid hypermetabolic uptake in the right neck base mass (arrowhead) and within the metastatic lymph nodes within the neck and chest (arrows)
