目的 探讨组织细胞坏死性淋巴结炎(KFD)的超声特征.方法 回顾性分析经病理证实为KFD患者的35个淋巴结图像,观察其二维及血流特点,以及超声造影灌注模式和造影剂分布情况.结果 35个淋巴结二维超声均呈低回声,未见钙化;最大长径(1.8±0.4) cm (0.8～3.3cm);48.6％L/S＜2;68.6％淋巴门可见;37.1％周边软组织回声增强;2.9％内见无回声;85.7％血流信号为淋巴门型;超声造影主要为离心性和弥漫性增强的模式;达峰时88.6％淋巴结均匀增强(31/35),11.4％淋巴结不均匀增强(4/35).结论 组织细胞坏死性淋巴结炎的二维超声表现与恶性淋巴结病变有一定重叠,但超声造影更符合了良性淋巴结病变,可为诊断提供有价值的参考信息.“,”Objective To analyze the ultrasonographic characteristics of lymphadenitis in (Kikuchi-Fujimoto disease,KFD).Methods 35 node of 35 cases KSD lymphadenitis which with pathology proof,their ultrasonography images were reviewed.The character of two-dimensional and Doppler images were observed.Each case carry out contrast enhanced ultrasound,the contrast agent perfusion pattern and distribution uniformity were observed.Results All of 35 lymph nodes[(0.8-3.3)cm;mean,(1.8±0.4)cm] showed hypoechoic,and none showed calcification.17 cases (48.6％) have a ration with long axis/ short axis(L/S)＜2.68.6％ had an echogenic hilum,and 37.1％ showed increased perinodal echogenicity.Cystic necrosis was seen in 1 cases(2.9 ％),and hilar vascularity was seen in 30 cases (85.7％).There were two types shown on CEUS:from central to margin and diffuse enhanced.Ultrasound.Homogeneous enhancement was observed in 31 of 35 nodes,other four node showed intense inhomogeneous enhancement.Conclusions Ultrasonic manifestation of KFD and malignant lymph nodes have some overlap,but CEUS of KFD conforms to the benign lymphadenopathy,provide reference value for diagnosis of information.
