Abstract
Objective: The aim of this study was to describe the characterization of metastatic cervical lymph nodes on computed tomography in papillary thyroid carcinoma and to evaluate the role of computed tomography in the diagnosis of lymph node metastasis in the neck region of papillary thyroid carcinoma.
Materials and Methods: Forty-four patients diagnosed with papillary thyroid carcinoma from January 2018 to July 2020 underwent computed tomography with intravenous iodine-containing contrast media to evaluate each group of cervical lymph nodes. The patients then had lymphadenectomy. We correlated the postoperative histopathological features with the imaging findings on computer tomography.
Results: The imaging findings of metastatic lymph nodes on computed tomography had low sensitivity, but the specificity was over 85%, the diagnostic value was in the range of 50-80%. The signs of round shape, strong and heterogenenous contrast enhancement, calcification, and cystic change were strongly correlated with lymph node metastasis (p <0.05).
Conclusion: The imaging findings on computed tomography had highly accurate in the diagnosis of metastatic cercial lymph nodes in papillary thyroid carcinoma. Computed tomography was proven valuable in the pre-operative diagnosis and management.
