【摘要】：目的探讨甲状腺峡部乳头状癌(PTC)声像图表现。方法回顾性分析103例峡部及270例侧叶PTC患者,根据结节位置分组:I_1组(PTC仅位于峡部)、I_2组(伴侧叶PTC的峡部PTC)、L_1组(PTC仅位于侧叶)和L2组(I2组患者的侧叶PTC)。结果 I_1组和I_2组超声诊断符合率为79.9%和83.3%低于L_1组91.7%。与L_1组相比,I_1组PTC多表现为边缘规则、纵横比1、回声均匀、甲状腺背景回声不均匀,I_1组结节接触和突破被膜比例、病理证实侵犯被膜比例、合并颈部淋巴结转移率也更高,差异有统计学意义(P0.05)。结论峡部PTC超声表现与侧叶PTC有所不同,结节与被膜关系更紧密,易发生淋巴结转移。
[Abstract]:Objective to investigate the ultrasonographic features of thyroid isthmus papillary carcinoma (PTC). Methods 103 cases of isthmus and 270 cases of lateral lobe PTC were analyzed retrospectively. Group I_1 (PTC only in isthmus), I_2 group (PTC isthmus PTC), L_1 group (PTC only in lateral lobe) and L2 group (lateral lobe PTC) in I2 group. The coincidence rate of 79.9% and 83.3% was lower than that of group 91.7%. in group L_1 and group L_1, PTC in group I_1 showed marginal rule, the ratio of vertical and horizontal ratio was 1, the echo was uniform, the echo of thyroid background was unevenly, the proportion of nodule contact and breakthrough membrane in group I_1, pathology confirmed the proportion of invasion of the membrane, and the rate of cervical lymph node metastasis was also higher, the difference was statistically significant (P0.05). The PTC findings of isthmus are different from those of lateral lobe PTC. The nodules are more closely related to the capsule and are prone to lymph node metastasis.
