Background:
No study on ultrasound-guided fine-needle aspiration (US-FNA) for the diagnosis of retrojugular lymph node has been reported. The present study aimed to introduce US-FNA techniques for retrojugular lymph node and to evaluate their efficacy.
Methods:
Of the 788 patients who underwent US-FNA of the cervical lymph node, 41 patients underwent US-FNAs of retrojugular lymph node and were included in this study. The adequacy and efficacy of US-FNA of retrojugular lymph node and related complications during or after the procedure were assessed.
Results:
Of the 41 patients, 35 (85.4%) were adequately diagnosed in cytological analysis; four predominantly cystic lymph nodes were identified. Based on cytohistopathology results, thyroglobulin measurement, tuberculosis polymerase chain reaction, and sonographic follow-up, malignant (n = 26) and benign (n = 15) lymph nodes were confirmed. When six lymph nodes with inadequate cytology were classified as benign and malignant, the sensitivity, specificity, positive and negative predictive values, and accuracy of US-FNA in differentiating malignant from benign lesions were 69.2% and 92.3%, 100% and 100%, 100% and 100%, 65.2% and 88.2%, and 80.5% and 95.1%, respectively. No substantial complications related to the US-FNA procedure were observed.
Conclusions:
The present US-FNA method may be helpful for the diagnosis of retrojugular lymph node.
