摘要
目的探讨甲状腺微小乳头状癌(PTMC)的声像图特点,提高术前诊断水平。方法回顾性分析68例共75个病灶经手术和病理证实的PTMC彩色多普勒超声图像特点。结果 68例PTMC患者中双侧病灶者7例,45例(66.2%)伴淋巴结转移。75个病灶中,70个(93.3%)呈低回声或极低回声,5个(6.7%)为等回声,病灶纵/横≥1的42例(56.0%),伴细小钙化55个(73.3%),血供I型或II型53个,占70.7%。结论低回声或极低回声、微钙化、纵/横≥1是PTC具有特征性的超声表现,掌握PTMC的超声特征表现,能提高检出率,从而为临床提供更有价值的信息。
Objective To explore the sonographic characteristics of papillary thyroid carcinoma （PTMC）, so as to im- prove the preoperative diagnostic level. Methods The characteristics of color Doppler ultrasound images of 68 patients with PTMC, with a total of 75 lesions, which were confirmed by pathology and operation, were retrospectively analyzed in this work. Results Of these 68 PTMC patients, 7 eases presented with bilateral lesions, 45 eases （66.2 %） were associat- ed with lymph node metastasis. Of these 75 lesions, 70 （93.3%） were shown low or lower echo, 5 （6.7%） were shown equal echo. Longitudinal / transverse lesions more than ≥ 1 were found in 42 cases （56 %）, lesions with small calcifica- tion were found in 55 （73.3 %）, and the blood supply of type I or Type II were found in 53, accounting for 70.7 %. Con- clusion Low echo or extremely low echo, micro-calcification, vertical and horizontal lesions more than 1 were the charac- teristic sonographic manifestations of PTC. Mastering these ultrasound features of PTMC can not only improve the detec- tion rate, but provide more valuable information for clinic as well.
