Abstract:
Objective To investigate the value of ultrasonic diagnosis on cervical lymph nodes metastasis regions and characteristics in thyroid carcinoma.Methods Ultrasound image of 290 patients with thyroid carcinoma were analyzed restrospectively.The cervical lymph node metastasis regions diagnosed by ultrasonography were compared with histopathologic results,and the ultrasound characteristics of metastasis lymph nodes were assessed.Results Among 290 patients,167 cases with cervical lymph node metastasis were comfirmed by pathology (57.6％),and 185 cases were detected by pre-operative ultrasound (63.8％).The region of thyroid carcinoma lymph node metastasis comfirmed by histopathology was most commonly the central region (54.1％),followed by the lateral neck (20.7％).The diagnostic rate of central region lymph node metastatic by pre-operative ultrasound was only 31.7％,which was sharply lower than that of lateral region (57.6％,P ＜0.05).However,the diagnostic specificity (72.8 ％) was apparently higher than lateral region (35.9％,P ＜0.05).The ultrasonic characteristics of metastatic cervical lymph nodes included rounded shape,absence of echogenic hilus,presence of calcitication,hyperechogenicity and cystic change.Conclusions The cervical central region is the predominant region for thyroid carcinoma lymph node metastasis,and ultrasound diagnosis on central region lymph node metastasis possesses positive specificity but negative sensitivity.Improving ultrasound diagnostic accuracy on central lymph nodes metastasis would be of important clinical significance.
