Abstract:
Thyroid cancer has a high morbidity in recent years, especially papillary thyroid cancer (PTC). Though the prognosis of PTC is generally decent, metastatic lymph nodes(MLN) may exist at the time of clinical diagnosis in some patients, which are currently considered one of important risk factors for tumor recurrence. Conventional ultrasonography gray scale mode can evaluate the morphology, size, boundary, internal echo and flow mode of thyroid nodules and cervical lymph nodes. Combining with dynamic enhancement mode and quantitative parameter evaluation of contrast-enhanced ultrasound (CEUS), qualitative judgment and quantitative determination of nodules hardness with ultrasound elastography, cytopathology and molecular detection with ultrasound-guided fine needle aspiration cytology, the diagnosis of cervical MLN of PTC has been greatly improved. The advancements of ultrasonography in evaluation of cervical MLN of thyroid cancer were mainly reviewed in this article.
