目的探讨甲状腺癌的超声图像特征及其病理学基础。方法回顾分析32例甲状腺癌患者的术前超声图像特征。结果超声肿块检出率94.7%,病灶诊断符合率65.8%,隐匿性癌诊断率16.7%。超声的图像特征主要有:肿块呈实质性低回声,形状不规则,边界不清,肿块内出现微小钙化灶。多发型甲状腺癌均为乳头状癌。结论超声应作为甲状腺癌的首选检查方法,检查时注意隐匿性癌的诊断,特别要重视乳头状癌的多灶性,这样可提高甲状腺癌术前诊断和评估的准确性。
Objective To investigate the characteristics of ultrasound and its pathology in thyroid cancer. Methods Retrospective analysis of 32 cases of thyroid cancer in patients with preoperative ultrasound image features. Results The detection rate of ultrasonic mass was 94.7%, the coincidence rate of lesions was 65.8%, and the occult carcinoma was 16.7%. Ultrasound image features are: mass was low hypoechoic, irregular shape, the boundary is unclear, there is a small calcification within the tumor. Multiple thyroid cancer are papillary carcinoma. Conclusion Ultrasound should be the first choice of thyroid cancer examination, the diagnosis of occult cancer pay attention to pay special attention to multifocal papillary carcinoma, which can improve the accuracy of preoperative diagnosis and evaluation of thyroid cancer.
