Her CT neck scan with intravenous contrast showed an enlarged, probably malignant thyroid gland with a marked amount of adjacent pathologic lymph nodes and marked transverse narrowing of the trachea to approximately 8.6 mm with no retrosternal extension (Figure 1).
Following chemotherapy, the patient's CT neck scan with contrast showed a significant decrease in the thyroid size measured approximately 4.2 x 4.2 cm, with marked improvement in tracheal narrowing.
