It is well known that the incidence of lymph node (LN) metastasis in differentiated thyroid cancer (DTC) is 20-50% and is associated with recurrence after surgery
.

Stripping neck LNs can improve the success rate of surgery , which in turn can reduce the risk of disease recurrence

It is well known that the incidence of lymph node (LN) metastasis in differentiated thyroid cancer (DTC) is 20-50% and is associated with 20-50% recurrence after surgery .

Ultrasound (US) is the main imaging modality for preoperative assessment of cervical LN metastasis in DTC patients

A study published in the European Radiology journal explored the correlation of clinical and ultrasonographic features as indicators of indeterminate metastatic LNs to further define the clinical indication for fine needle aspiration (FNA) .

This study retrospectively investigated consecutive patients who underwent US-guided FNA between January 2014 and December 2018 for indeterminate LNs for differentiated thyroid cancer on ultrasound .
According to the Korean Society of Thyroid Radiology (KSThR) guidelines, indeterminate LNs are defined as LNs with neither fat mounds nor blood vessels in the absence of any suspicious findings .
Univariate and multivariate logistic regression analyses were performed to identify important risk factors associated with malignancy in LNs .

Of the 236 LNs in the 212 patients enrolled in this study, 67 LNs (28.

3%) were metastatic

In conclusion, given the relatively high, malignancy risk (28.
