History of paralaryngeal circumferential mass with pathology consistent with metastatic thyroid carcinoma status post RAI with no response. There are postoperative findings related to total thyroidectomy and neck dissection. There is interval increase in size of the right tracheoesophageal groove nodule that appears indistinct from the adjacent trachea and esophagus, which now measures 15 x 25 mm, previously 5 x 12 mm. There is an infiltrative enhancing mass posterior to the lower larynx, in which the dominant portion on the left side measures approximately 15 x 20 mm, previously 14 x 18 mm. Likewise, an infiltrative tumor in the posterior visceral space that appears to indent and perhaps invade the upper trachea and esophagus has increased in size, now measuring 18 x 30 mm, previously 15 x 20 mm. There also a prominent left level 4 lymph node that measures 10 mm in short axis, previously 7 mm. The salivary glands are unremarkable. There is mild multilevel degenerative spondylosis and subcentimeter bilateral neural foramen perineural cysts at T1-2. The imaged intracranial structures are unremarkable. There are bilateral lens implants.
Postoperative findings related to total thyroidectomy and neck dissection with overall increase in size of the multiple foci of recurrent tumor in the lower neck.
