Initial Ultrasound Criteria for the Diagnosis of Cervical Lymph Node Metastases from Papillary Thyroid Cancer

Introduction: Cervical lymph node metastases from papillary thyroid cancer were classified into three categories according to ultrasound: 1) Metastases not visible on ultrasound; 2) met initial criteria for the diagnosis; 3) typical diagnosis. Purpose: To develop ultrasound diagnosis of cervical cancer. Material and methods: We studied groups nodes in patients with The first group consisted 4307 that ultrasound. However, some them histology revealed a metastasis. second 242 metastases, third one comprised 17 causing signs. Ultrasound imaging was performed by use standard machines are widely used clinical practice. presence confirmed cytology. Results: According histological data, present 961 (22.3 %) level VI located fatty tissue removed disease prevention. These missed ultrasound, so remained undetected. Typical were: an additional space-occupying lesion neck, local fat deformation, depth/width ratio over 0.5, no differentiation between cortical cerebral layers, predominance nature, avascularity, calcifications. extranodal extension showed changes shape outlines, metastatic spread adjacent tissue, muscles vessels. Initial sonographic features helped identify metastasis included microcalcifications nodal occupying part layers being seen as hyperechoic or cavity fluid, mixture fluid. round ovoid shape. There early metastases. 0.5–0.7 cm size. Conclusion: can detect cause Besides, it helps guide biopsies.
