摘要
目的:探讨甲状腺微小癌(TMC)的声像图特征。方法:34例患者术前行高频超声检查,术后与手术和病理对照。结果:32例(88.2%)低回声,30例(88.2%)结节纵/横≥1,26例(76.5%)伴微钙化,23例(67.6%)毛剌边缘,29例(85.3%)结节单发,20例(58.8%)边界不清晰,14例(41.2%)侧后方声影,6例(17.6%)检出血流信号,8例(23.5%)颈淋巴结肿大。出现上述异常声像图特征2项以上者占73.5%(25/34)。结论:对单发灶及长期随访结节性甲状腺肿患者的甲状腺内发现直径在1cm以内的低回声伴钙化,CD-FI显示血流信号较丰富,应警惕甲状腺微小癌的可能,并仔细扫查颈部淋巴结。
Objective：To explore the ultrasonography feature of tiny thyroid papillary thyroid carcinoma（PTC）.Methods：Ultrasound image and pathology of 34 PTC patients were retrospectively analyzed.Results：The rate of hypoechoic was 88.2 %（30/34）.The rate of aspect ratio（≥1） for nodular was 88.2%（30/34）.The rate of microcalcifications was 76.5 %（26/34）.The rate of nodular with burr edge was 67.6%（23/36）.The rate of single nodule was 85.3%（29/34）.The rate of nodular with boundary unclear was 58.8%（20/34）.The rate nodular with monitors sound shadow was 41.2%（14/34）.There was blood flow signal in 6 cases（17.6%） and lymph nodes were positive in 8 cases（23.5%）.The rate of patient with more than two abnormal ultrasonographic features was 73.5%（25/34）.Conclusion：Hypo-echo nodules,regular shape,irregular edges and calcification are the ultrasound characteristic.Comprehending the characteristics may improve the pre-operation diagnosis efficacy.
