Abstract:
Purpose To explore CT manifestations of thyroid carcinoma and its correlation with neck lymph node metastasis. Materials and Methods CT findings of 165 patients with thyroid carcinoma confirmed by surgical pathology were studied, including number, shape, size, calcium, necrosis, surrounding invasion and enhancement of substantial part, and its correlation with neck lymph node metastasis was also analyzed. Results 107 out of 165 patients (64.85%) suffered from neck lymph node metastasis. Different tumor number, calcium and necrosis were not associated with the rate of neck lymph node metastasis (χ2=0.009, 2.606, 1.522;P>0.05);tumor shape, size, surrounding invasion and enhancement were significantly different from the rate (χ2=26.510, 75.995, 68.922, 20.819;P<0.05). Patients age, tumor shape, size, enhancement and surrounding invasion were positively correlated with lymph node metastasis (r=0.124, 0.243, 0.276, 0.287, 0.395;P<0.05);the sequence of correlation was as follows:surrounding invasion>enh ancement>shape>size>age. However, patients gender, tumor number, calcium and necrosis showed on correlation (r=0.074, 0.126, 0.005, 0.121;P>0.05). Conclusion Lymph node metastasis is mainly associated with factors like age, tumor shape, size, enhancement and surrounding invasion. It is advisable that patients with high risk rate may consider selective cervical lymph node dissection.
