摘　　要：目的探讨甲状腺转移癌(TM)的临床特点、超声特征和其诊断价值。方法回顾分析16例经术后病理证实的TM患者的超声声像图特征和临床资料。结果 16例患者的原发病灶依次为食管癌5例(31.2%),乳腺癌3例(18.7%),肺癌3例(18.7%),肾癌2例(12.5%),黑色素瘤2例(12.5%),前列腺癌1例(6.2%)。TM超声表现分别为结节型(81.3%)和弥漫浸润型(18.7%)。结节型TM超声声像图特征:76.5%(13/17)形态不规则;64.7%(11/17)边界不清;70.6%(12/17)实性低回声;41.2%(7/17)侵犯甲状腺包膜,呈浸润性生长;52.9%(9/17)钙化;70.5%(12/17)血流信号丰富。弥漫型TM甲状腺实质呈弥漫性不均匀低回声,没有明确边界,血流信号丰富。37.5%(6例)患者伴颈部淋巴结转移。结论 TM的超声声像图具有一定的特征性,结合其临床资料有助于提高诊断准确率。Objective To analyze the clinical and ultrasonic features of thyroid metastatic carcinoma(TM) and diagnostic value of ultrasonography(US) in TM. Methods The ultrasonographic features and clinical data of 16 patients with TM confirmed by postoperative pathology were retrospectively analyzed. Results The primary lesions of 16 patients were esophageal cancer in 5 cases(31.2%), breast cancer in 3 cases(18.7%), lung cancer in 3 cases(18.7%), renal cell carcinoma in 2 cases(12.5%), melanoma in 2 cases(12.5%), prostate cancer in 1 case(6.2%). The sonographic features of TM were nodular(81.3%) and diffuse infiltrative(18.7%). Nodular TM sonographic features: 76.5%(13/17) with irregular shape;64.7%(11/17) with unclear boundary;70.6%(12/17) with solid hypoechoic;41.2%(7/17) with thyroid capsule invasion and infiltrative growth;52.9%(9/17) with calcification;70.5%(12/17) with rich blood flow signal. The thyroid parenchyma of diffuse type TM showed diffuse heterogeneous hypoechoic, no clear boundary, and abundant blood flow signals. Six percent(6 cases) of the TM patients were with cervical lymph node metastasis. Conclusions The ultrasonic image of TM has certain characteristics, and it is helpful to improve the accuracy of diagnosis combined with its clinical data.
