Abstract | OBJECTIVES: METHODS: The study population consisted of 104 consecutively registered patients who had undergone thyroidectomy for papillary thyroid carcinoma and underwent sonographically guided fine-needle aspiration of lymph nodes in the neck. The sonographic features of each lymph node were retrospectively evaluated by a single radiologist. The confirmation methods for the 115 lymph nodes included surgery (n = 35), measurement of thyroglobulin levels in the aspirates (n = 2), malignant cytologic analysis (n = 10), and benign cytologic analysis with sonographic follow-up over 12 months (n = 68). We determined the diagnostic indices of individual sonographic features for differentiating between metastatic and benign lymph nodes by comparing these features with the final diagnoses. RESULTS: Of the 104 patients, 67 underwent at least 1 cycle of radioisotope therapy after thyroidectomy. The malignancy rate for the lymph nodes was 42.6% (49 of 115). A significant relationship was found between malignancy and the presence of an intranodal cystic component, intranodal microcalcifications, diffusely increased echogenicity, a microlobulated margin, a round shape, loss of echogenic hila, and mixed or central vascularity on color Doppler sonography (P < .05). CONCLUSIONS: The sonographic features of metastatic cervical lymph nodes in postoperative patients with papillary thyroid carcinoma were similar to those in preoperative patients.
