摘要：

目的 分析甲状腺乳头状微癌高频彩色多普勒超声声像图的表现特点。方法 收集57例术前接受高频彩色多普勒超声检查且经术后病理学检查证实为甲状腺乳头状微癌患者的临床资料，对超声声像图进行回顾性描述并分析和归纳其特征性表现。结果 57例患者中，术前超声诊断甲状腺乳头状微癌52例（其中伴颈部淋巴结肿大7例），甲状腺腺瘤2例，结节性甲状腺肿3例；术前超声诊断与术后病理学诊断的符合率为91.2%。二维超声发现直径4~10 mm的结节68个，其中61个（89.7%）呈实性低回声，57个（83.8%）结节内有微钙化灶，49个（72.1%）边界不清，45个（66.2%）形态不规则。彩色多普勒血流显像发现55个（80.9%）结节内少量点状血流信号，结节周边无明显血流信号。结论 甲状腺乳头状微癌高频彩色多普勒超声声像图表现为形态不规则、边界不清的实性低回声结节，并存在结节内微钙化灶。病变早期小结节及有良性疾病病灶并存时，应注意与甲状腺腺瘤和结节性甲状腺肿相鉴别。

Abstract:

Objective To analyse the characteristics of high frequency color Doppler ultrasound images of thyroid papillary microcarcinoma. Methods The clinical data of 57 cases which underwent high frequency color Doppler ultrasound examinations before operation and were confirmed as thyroid papillary microcarcinoma by pathological examinations after operation were collected, the characteristics of ultrasound images were retrospectively described and analysed. Results Among the 57 cases, 52 were diagnosed as thyroid papillary microcarcinoma (cervical lymphadenectasis in 7), 2 were diagnosed as thyroid adenoma and 3 were diagnosed as nodular goiter by ultrasound before operation. The coincidence between ultrasound diagnosis before operation and pathological diagnosis after operation was 91.2%. Sixty-eight nodes with diameter of 4 to 10 mm were found by two dimensional ultrasound, among which 61 (89.7%) presented low echo, 57 (83.8%) had microcalcification, 49 (72.1%) had irregular margin and 45 (66.2%) exhibited irregular morphology. Color Doppler ultrasound revealed small amount of dotted blood flow signal in 55 nodes (80.9%), with no obvious blood flow signal around nodes. Conclusion High frequency color Doppler ultrasound images of thyroid papillary microcarcinoma were characterised by low echo nodes with irregular morphology, irregular margin and microcalcification in nodes, and should be differentiated from thyroid adenoma and nodular goiter.
