Imaging examination results. (A) The yellow arrows indicate the enlarged right cervical lymph nodes, which were suspicious for metastasis. (B) CT showed an oval mass with low attenuation in the right lobe of the thyroid and a round nodule with discontinuous peripheral annular calcification. (The yellow arrow indicates the tumor; the green arrow indicates the tumor focally broke into the nodule below and caused the interruption of the annular calcification; the red arrow indicates airway deviation caused by tumor compression). (C) The yellow arrow indicates the left lobe of the thyroid gland; the red arrow indicates airway deviation caused by tumor compression; the green arrow indicates a nodule with interruption of the annular calcification.. Abbreviation: CT, computed tomography.
