摘　　要：目的探讨甲状腺包膜内滤泡型乳头状癌(EFVPTC)的超声表现,分析其超声误诊原因。方法回顾分析31例经手术及病理证实的EFVPTC患者的超声表现,结合病理结果进行对照分析。结果 31例EFVPTC患者的超声表现可分为两种:①Ⅰ型15例(48.4%),表现为境界较清晰的等回声或低回声结节,其形态不规则,边缘可见成角或分叶,微小钙化较少见;②Ⅱ型16例(51.6%),表现为形似腺瘤,结节边界清晰且边缘光整,内部为均匀中等回声。31例中有6例(19.4%)发现颈部淋巴结转移,超声表现为高回声,内可见微小钙化及囊性变。超声提示甲状腺恶性肿瘤9例,误诊22例,诊断符合率为29%。结论甲状腺内单发的分叶状病灶及典型甲状腺乳头状癌转移淋巴结对提示诊断EFVPTC有较高价值。Objective To investigate the ultrasonic characteristics of encapsulated follicular variant of papillary thyroid carcinoma（EFVPTC）, and analyze the reasons for the misdiagnosis. Methods Data of ultrasound findings in 31 cases of EFVPTC confirmed by pathology were analyzed retrospectively. Results Ultrasonic characteristics of 31 cases were classified into two types：15 cases of type I （48.4%）,isoechoic or hypoechoic nodules with irregular shape,angled and lobular edge,with rare microcalcification; 16 cases of type （51.6% ）, with clear boundary and regular shape, and homogeneous inside. Cervical lymph nodes matastasis with hyperechoic cortex, microcalcification and cystic lesions were found in 6 cases （19.4%）. Nine cases were diagnosed correctly using ultrasonography, 22 cases were misdiagnosed,the accuracy was 29%. Conclusion Single lobular lesions and the typical features of lymph node metastasis are valuable to diagnose the EFVPTC.
