Persistent disease in a 43-year-old woman with bilateral thyroid cancers. (A) Axial CT image with a 60-s scan delay shows a small lymph node at left level III (arrow) without suspicious CT features before initial surgery. She underwent total thyroidectomy with central neck dissection. (B) Axial CT image with a 40-s scan delay shows a lymph node (arrow) with a strong enhancement at the same location before reoperation.
