Abstract：Thyroid cancer has a relatively high rate of lymph node metastasis.Ultrasound is the first imaging technique used for the assessment of cervical lymph node metastasis in patients with thyroid cancer.Enlarged axis,round shape,loss of an echogenic fatty hilum,cystic change,calcification,and abnormal vascularity are sonographic signs of metastatic lymph nodes.CT may be used as a complementary diagnostic method.Enlarged size,nodal grouping,calcification,cystic or necrotic change and abnormal enhancement suggest malignant possibility.Uhrasound guided fine needle aspiration cytology (FNAC) and thyroglobulin or calcitonin measurement in wash-out fluid of FNA has satisfactory diagnostic performance in lymph node metastasis.
