Objective:To evaluate the value of multimodal ultrasound in cervical central lymph node metastasis(CLNM)of papillary thyroid microcarcinoma(PTMC).Methods:Clinical data and ultrasonic features of 110 PTMC patients who underwent thyroid surgery were collected.The risk factors for predicting cervical CLNM were analyzed.Results:Male and age<42 years old were more likely to develop cervical CLNM in PTMC(P<0.05).Transverse diameter≥0.52 cm or longitudinal diameter≥0.66 cm were high-risk factors for cervical CLNM(P<0.01).Microcalcifications and elastic scores≥4 points were more likely to develop central LNM in PTMC(both P<0.01).The multivariate analysis showed that microcalcification was an independent risk factor for cervical CLNM in PTMC.Conclusions:For PTMC patients with microcalcification within the nodules,preoperative evaluation and intraoperative treatment of cervical central lymph nodes should be strengthened.
