The whole right lobe and isthmus of thyroid gland have altered signal in keeping with diffuse infiltrative tumoral involvement. This is contiguous with soft tissue extending into the midline subcutaneous region and right strap muscles. Right anterolateral aspect of trachea shows abnormal signal intensity and right aspect of thyroid cartilage shows abnormal signal intensity and enhancement. There is an enhancing lymph node with isosignal intensity with thyroidal mass at left carotid space (metastasis). Multiple bilateral cervical and right paratracheal lymph nodes are noted too. Abnormal rim enhancing lesion at superior segment of RUL is seen.
