摘要
目的探讨弥漫硬化型甲状腺乳头状癌的声像图特征。方法回顾性分析经手术病理证实的11例弥漫硬化型甲状腺乳头状癌患者的甲状腺及颈部淋巴结声像图表现。结果病变累及双侧叶(6/11,54.5%)或单侧叶(5/11,45.4%),超声主要特征为患侧叶体积增大,实质回声增粗并弥漫性分布的沙砾样微钙化(11/11,100%),部分合并模糊低回声结节(3/11,27.2%),血流信号1-2级(81.8%)。9例手术证实伴有同侧颈部淋巴结转移(9/11,81.8%),转移淋巴结多伴微钙化(8/9,88.9%)及血流信号增多杂乱(7/9,77.8%)。所有病例术前超声均进行了正确的提示诊断。结论弥漫硬化型甲状腺乳头状癌具有较典型的声像特征,超声检查是提示该疾病的有用工具,可为临床诊断提供重要的参考依据。
Objective To investigate the ultrasonographic features of the diffuse sclerosing variant of papillary thyroid carcinoma(DSV-PTC). Methods Eleven cases of DSV-PTC confirmed by surgical pathology were enrolled in our study. Ultrasonic features of thyroid lesions and cervical lymph nodes were analyzed retrospectively. Results The lesions of DSV-PTC involved bilateral lobe(6/11, 54.5%) or unilateral lobe(5/11, 45.4%). On ultrasound, they were mainly characterized by increased lobe volume, thickened parenchyma and diffuse distribution of gravellike microcalcification.(11/11, 100%). Some cases own a combination of hypoechoic nodules with fuzzy boundary(3/11, 27.2%), and the blood flow signals showed grade 1-2(81.8%). Nine patients were confirmed to have ipsilateral cervical lymph node metastasis(9/11, 81.8%), and the metastatic lymph nodes accompanied with microcalcification(8/9, 88.9%) and increased blood flow signal(7/9, 77.8%). All cases were correctly diagnosed by preoperative ultrasonography. Conclusion DSV-PTC possesses typical ultrasonographic characteristics and can provide an important reference for clinical diagnosis.
