【摘要】 目的探讨二维及彩色多普勒超声对甲状腺微小乳头状癌(papillary thyroid carcinoma,PTC)的声像图特征。方法回顾分析36例PTC患者的声像图特征并与病理结果对照。结果 35例(97.2%)结节纵/横≥1,30例(83.3%)伴微钙化,34例(94.4%)低回声,29例(80.6%)单发,19例(52.8%)边界清晰,23例(63.9%)毛刺边缘,17例(47.2%)侧后方声影,4例(11.1%)血流相对丰富,32例(88.9%)无明显血流信号,35例(97.2%)实质性,8例(22.2%)颈淋巴结肿大。具备上述异常声像图特征2项以上者占66.7%(24/36),单项者占91.7%(33/36)。超声与病理结果符合率为86.1%(31/36),不符合率为13.9%(5/36)。结论长期随访的单发低回声病灶<1.0 cm伴微钙化、边缘毛剌者,必须警惕PTC的可能,并注意颈淋巴结的扫查,单项血流不建议作为PTC的诊断标准。更多还原

【Abstract】 Objective To explore the two-dimensional ultrasound and color Doppler ultrasonography feature of tiny thyroid papillary thyroid carcinoma(PTC).Methods Ultrasound image and pathology of 36 PTC patients were retrospectively analyzed.Results The rate of aspect ratio(≥1) for nodular was 97.7%(35/36).The rate of single nodule was 80.6%(29/36).The rate of microcalcifications was 83.3%(30/36).The rate of hypoechoic was 94.4% (34/36).The rate of nodular with boundary clear was 52.8%(19 /36).The rate of nodular with burr edge was 63.9%(23/36) and the rate nodular with monitors sound shadow was 47.2%(17/36).The blood flow in four cases (11.1%) was richer than other cases and there is not obvious blood flow signal in 32 cases(88.9%).The image was substantial in 35 cases(97.2%).Lymph nodes were positive in 8 cases(22.2%).The rate of patient with more than two abnormal ultrasonographic features was 66.7%(24/36) and the rate of patient with one abnormal ultrasonographic feature was 91.7%(33/36).The coincidence rate of ultrasound and pathological was 86.1%(31/36) and misdiagnosis rate was 13.9%(5/36).Conclusions Patients of PTC must be alerted to these items when single nodule or hypoechoic lesions less than 1 cm or with microcalcification or burr edge.Lymph node should be scanned conventional for these patients.Only blood flow is not accurate enough as diagnose of PTC.更多还原
