摘要
目的:探讨甲状腺微小癌(TMC)的超声声像图特点。材料和方法:2003年1月至2005年1月71例甲状腺微小癌住院患者,其中男性17例,女性54例,男女比例为1:3.18,年龄26～77岁,平均49.6岁。所有患者的超声检查在手术前1周内进行,均经手术和病理证实。分析病灶多少、大小、内部回声类型、钙化、内部血流信号、颈淋巴结肿大等超声征象。结果:检出多发性病灶32例,检出单发性病灶35例,漏诊4个(10.3%),病灶检出率89.7%(35/39)。结论:对单发灶及长期随访结节性甲状腺肿患者的甲状腺内发现直径在1cm以内的低回声伴钙化,CDFI显示血流信号较丰富,必须警惕甲状腺微小癌的可能,并仔细扫查颈部淋巴结。
Purpose： To investigate the characteristics of thyroid microcarcinoma （TMC） with ultrasonography （US）. Materials and Methods：The following ultrasonography characteristics of the thyroid nodules in 71 cases of thyroid microcarcinoma from Jan 2003 to Jan 2005 were retrospectively analyzed： size, number, echogenicity, microcalcifications, and types of vascularization. Results： 32 cases of multiple thyroid nodules were excluded out of the discuss, because the hiding malignant lesions were too difficult to be confirmed and compared with the others by the US. 35 single thyroid nodules were detected by US, 4 were missed diagnosis , US detective ratio were 89.7% （35/39）. Conclusion： The middle - aged women, especially with single thyroid nodules or with long - term clinical and US follow - up history of nodular goiter, must be alerted the potential of thyroid microcarcinoma, with the detection of thyroid nodules with diameter of 10mm and smaller, hypoechogenicity, microcalcifications, increased intranodular vascularization and cervical lymph nodes.
