目的:探讨颈部第Ⅵ组淋巴结在桥本甲状腺炎超声鉴别诊断中的价值。方法:选取甲状腺弥漫性疾病患者188例,根据临床诊断分为桥本甲状腺炎和其他弥漫性病变2组,其中桥本甲状腺炎组98例,其他弥漫性病变组90例。采用二维超声和彩色多普勒超声检查所有患者的双侧甲状腺形态、回声均匀性及彩色血流特征,同时观察其颈部第Ⅵ组淋巴结是否显示。结果:98例桥本甲状腺炎患者中有76例颈部第Ⅵ组淋巴结显示,90例其他弥漫性病变患者中有12例颈部第Ⅵ组淋巴结显示,2组差异有统计学意义(P<0.05),其灵敏度、特异度和准确率分别为77.6%、86.7%和81.9%,阳性预测值和阴性预测值分别为86.4%和78.0%。桥本甲状腺炎组中有颈部第Ⅵ组淋巴结显示者明显多于其他甲状腺弥漫性病变组。结论:颈部第Ⅵ组淋巴结在桥本甲状腺炎的超声鉴别诊断中有一定价值,可辅助判断甲状腺弥漫性病变的性质。
Objective: To investigate the value of cervical Ⅵ lymph nodes in the differential diagnosis of Hashimoto’s thyroiditis. Methods: A total of 188 patients with thyroid diffuse disease were selected and divided into two groups according to clinical diagnosis: Hashimoto’s thyroiditis and other diffuse lesions, including 98 Hashimoto’s thyroiditis patients and 90 other diffuse disease patients. Two-dimensional ultrasound and color Doppler ultrasound examination of bilateral thyroid morphology, echo uniformity and color flow characteristics of all patients, while observing the neck Ⅵ group of lymph nodes are displayed. Results: Of the 98 Hashimoto’s thyroiditis patients, 76 cases of cervical lymph node group Ⅵ showed that in the 90 cases of other diffuse lesions, 12 cases of cervical Ⅵ group of lymph nodes showed significant difference between the two groups (P < 0.05). The sensitivity, specificity and accuracy were 77.6%, 86.7% and 81.9% respectively. The positive predictive value and negative predictive value were 86.4% and 78.0% respectively. Hashimoto’s thyroiditis group neck Ⅵ group of lymph nodes was significantly more than other thyroid diffuse lesions. Conclusion: Group Ⅵ cervical lymph nodes in Hashimoto ’s thyroiditis ultrasound differential diagnosis of some value, can help determine the nature of diffuse thyroid lesions.
