【摘 要】目的:探讨超声在甲状腺髓样癌诊断中的应用价值。方法:选择我院2017年10月-2019年10月收治的14例依據手术及细针穿刺病理结果确诊的甲状腺髓样癌患者作为研究对象,通过分析其术前超声甲状腺结节的数量、位置、内部回声特点、形态、边界、纵横比、有无钙化、血供等特点,分析甲状腺髓样癌的超声特征。结果:甲状腺髓样癌多单发,位于甲状腺中上段,血流丰富,可伴有无钙化的转移性淋巴结。结论:甲状腺髓样癌的特征性超声表现结合血清降钙素的升高能为患者的早期诊断提供帮助,从而改善患者的预后。

【Abstract】Objective: To explore the value of ultrasonography in the diagnosis of medullary thyroid cancer.Methods: 14 patients treated in our hospital from October 2019 to October 2017- according to the results of surgery and fine needle biopsy in diagnosis of medullary thyroid carcinoma patients as the research object, through the analysis of the preoperative ultrasound of thyroid nodule number, location and internal echo characteristics, morphology, boundary, aspect ratio, with or without calcification and blood supply, analyze the ultrasonic features of medullary thyroid carcinoma.Results: Medullary thyroid carcinoma was mostly single, located in the middle and upper thyroid, with abundant blood flow and metastatic lymph nodes without calcification.Conclusion: The characteristic ultrasonographic features of medullary thyroid carcinoma combined with elevated serum calcitonin can help in the early diagnosis and improve the prognosis of patients.

甲状腺髓样癌约占甲状腺癌的4%,它来源于泌降钙素的滤泡旁细胞,是一种神经内分泌肿瘤,能分泌降钙素、癌胚抗原及其他多肽类激素,容易转移和复发,预后差。甲状腺髓样癌对放化疗不敏感,早期手术切除是提高患者生存率的有效措施,因此,提高超声检查对甲状腺髓样癌的早期诊断尤为重要。
1 资料与方法
1.1 一般资料 分析2017年10月-2019年10月在我院超声科行甲状腺超声检查并手术病理确诊为甲状腺髓样癌的14例患者,均为单发结节,其中男性4例,女性10例。年龄28~72岁,平均年龄(51.23+6.76)岁。
1.2 方法 采用等超声仪器进行超声检查,通过分析甲状腺结节的数量、位置、内部回声特点、形态、边界、纵横比、有无钙化、血供等特点,对甲状腺髓样癌的特点进行分析。血流信号按ALder进行分级:0级,结节周边及内部未见明显血流信号;Ⅰ级,结节周边可见丰富血流信号;Ⅱ级,结节周边及内部血流信号不足50%区域;Ⅲ级,结节内部血流信号至少达到50%区域。……
