彩色多普勒超声在结节性甲状腺肿的诊断应用

Color doppler ultrasonography in the diagnosis of nodular goiter application

目的通过病例分析提高结节性甲状腺肿的声像图诊断率。方法回顾性分析经手术及病理证实的26例结节性甲状腺肿的彩色多普勒超声声像图表现。结果26例病例中,实性肿块11例,混合性肿块5例,囊性肿块2例,实性肿块与囊性肿块并存2例,实性肿块与混合性肿块并存6例。结论①在甲状腺一侧叶或双侧叶内出现多个实性、囊性和混合回声结节时,应首先考虑结节性甲状腺肿;②对单个较大囊性结节、囊实混合性结节,结合囊壁厚度、包膜是否完整、暗区内有无纤维间隔光带及乳头样突起等表现,鉴别结节性甲状腺肿和腺瘤囊性变;③对实性结节,需根据结节内部回声、包膜是否连续、边界清晰度、有无声晕、后方回声有无衰减、结节内有无沙粒样钙化、肿块内部及周边血流等情况判断。

Objective In order to promote the diagnostic accordance rate of the nodular goiter. Methods Analyzed the contrast between the characteristics of images and pathologic results of 40 cases of nodular goiter. Results 26 cases of cases, 11 cases of solid tumor, 5cases of mixed tumor, 2 cases of cystic tumor, solid tumor and the coexistence of four cases of cystic tumor, solid tumor mass with mixed co-exist 6 Example. Conclusion ①It should be considered as nodular goiter first that many nodes was detected in thyriol; ②When single cystic node or mixed echo was detected in thyriod,judging the nodular goiter and thyroid adenoma with cystic lesions should be based on thickness of cystic wall, fiber interval in the liquid area, papillary protrusions within cysts;③In the situaton of solid nodules, the diagnosis of the goiter should be bases on the concrete characteristics of the images such as internal echoes, the continuity of capusles, the clearness of the boundray, the echo halo and rear attenuation.
