| 目的 探讨误诊为甲状腺乳头状癌（PTC）的结节性甲状腺肿（结甲）的声像图特点。方法 回顾性分析60例误诊为PTC的结甲的声像图特征，包括结节最大径、纵横比、边界、回声、囊性成分、微小强回声、粗大强回声、条带样中等回声及血供情况。回顾分析10例患者历史超声检查资料，观察甲状腺结节变化情况。另选取同期70例PTC作为对照，分析二者声像图特征的异同。结果 结甲与PTC在有无囊性成分、弥漫微小强回声、条带样中等回声方面差异有统计学意义（P均<0.05），在最大径、纵横比、边界、回声、散在微小强回声、粗大强回声和血供差异无统计学意义（P均>0.05）。结甲内部囊性区域可逐渐缩小。结论 多发微小囊性成分、条带样中等回声及结节呈动态变化有助正确诊断结甲。 |

| Objective To explore ultrasonic characteristics of nodular goiter mimicking papillary thyroid carcinoma (PTC). Methods Ultrasonic features of 60 nodular goiters misdiagnosed as PTC in 60 patients were retrospectively analyzed, including the longest diameter, anteroposterior to transverse dimension ratio (A/T), margin, echogenicity, cystic change, microcalcification, macrocalcification, inner isoechoic rim, vascularity and nodular changes. Meanwhile, 70 patients with pathologically confirmed PTCs were taken as controls. The similarities and differences between both diseases were evaluated. Results Cystic changes, microcalcification with diffused distribution and inner isoechoic rim were significantly different (all P<0.05), while the longest diameter, A/T, margin, echogenicity, microcalcification with scattered distribution, macrocalcification and vascularity were no significantly different between PTC and nodular goiter (all P>0.05). The cystic areas of nodular goiter gradually reduced. Conclusion Small and multiple cystic components, inner isoechoic rim and previous degenerative changes contribute to the differential diagnosis of nodular goiter from PTC. |
