摘要
目的:分析高频超声在颈部淋巴结结核诊断中的应用价值,为临床颈部淋巴结结核的准确诊断提供参考。方法:选取2017年—2021年在苏州市第五人民医院就诊的70例颈部淋巴结肿大患者作为研究对象,对其行手术病理检查和高频超声检查,以病理结果为金标准,分析高频超声检查在颈部淋巴结结核诊断中的灵敏度、特异度、漏诊率和误诊率。结果:70例患者中,有51例经高频超声检查被诊断为颈部淋巴结结核,其中有48例同时被病理检查认定为颈部淋巴结结核;高频超声检查在颈部淋巴结结核诊断中的灵敏度为87.27%,特异度为80.00%,漏诊率为12.73%,误诊率为20.00%,约登指数为67.27%;48例真阳性患者的高频超声图像特征表现为颈部淋巴结有呈串状排列,也有单发,外形趋圆形,L/T小于2,内部回声不均质,表现为低回声、无回声、强回声混杂,淋巴门偏移、狭窄或消失,淋巴结边界模糊,相互融合。结论:高频超声对颈部淋巴结结核的诊断具有较高的价值,可以较好地帮助临床医生进行准确诊断。
Objective:To analyze the application value of high-frequency ultrasound in the diagnosis of tuberculosis of cervical lymph nodes,and provide a reference for the accurate diagnosis of tuberculosis of cervical lymph nodes clinically.Methods:70 patients with enlargement of cervical lymph nodes who were treated in Suzhou Fifth People's Hospital from 2017 to 2021 were selected as the subjects,and they received surgical pathological examination and high-frequency ultrasonic examination.By using the pathological results as a gold standard,the sensitivity,specificity,missed diagnosis rate and misdiagnosis rate of high-frequency ultrasonic examination in the diagnosis of tuberculosis of cervical lymph nodes were analyzed.Results:Among 70 patients,51 cases were diagnosed with tuberculosis of cervical lymph nodes by high-frequency ultrasonic examination,and 48 of which were identified as tuberculosis of cervical lymph nodes by pathological examination.The sensitivity,specificity,missed diagnosis rate,and misdiagnosis rate of the high-frequency ultrasonic examination in the diagnosis of tuberculosis of cervical lymph nodes were 87.27%,80.00%,12.73%,and 20.00%,respectively;the Youden index was 67.27%;the high-frequency ultrasound image characteristics of 48 true-positive patients showed string-like arrangement of cervical lymph nodes,solitary,with a rounded shape,L/T less than 2,and internal echo inhomogeneity;they were manifested as a mixture of hypoecho,anecho,and strong echo,shift,narrowing or disappearance of lymph node hilus,and blurred boundaries and mutual fusion of lymph nodes.Conclusion:High-frequency ultrasound has a high value in the diagnosis of tuberculosis of cervical lymph nodes and can assist clinicians in making accurate diagnosis.
