Lymph node metastasis from thyroid cancer can present with lymph node calcification.
Papillary thyroid cancer presenting with lymph node metastasis needs to be reviewed periodically after treatment by surgery. If postoperative lymph node enlargement with calcification is found, the possibility of lymph node metastasis and intraoperative suture absorption over time leading to calcification needs to be considered. The nature, number, size, surrounding tissue relationship, and aspect ratio of the lymph nodes can be observed through neck ultrasound and lymph node aspiration biopsy to determine the benign or malignant tendency of the lymph nodes, but the pathological results should be the final outcome in determining the cause of lymph node enlargement and calcification.
If a postoperative review of a patient with thyroid cancer surgery reveals enlarged lymph nodes with calcification in the lateral neck, there needs to be a high suspicion of lymph node cancer metastasis. The first step is to assess the possibility of lymph node metastasis by ultrasound, but patients are still advised to have a fine needle aspiration to extract cells from the lymph nodes for pathological examination to see if there are malignant tumor cells, and if there are, the diagnosis of lymph node metastasis is confirmed and further treatment is needed. If there is no such thing, the patient still needs to be reviewed regularly.
