目的:探讨彩色多普勒超声在组织细胞坏死性淋巴结炎(Kikuchi-Fujimoto disease,KFD)诊断中的应用价值.方法:回顾性分析60例经活检或手术病理证实的KFD受累淋巴结的二维及彩色多普勒超声表现.结果:60例患者中颈部淋巴结受累者57例,占95.00%(57/60),其中多区域病变者54例,累及颈后三角区者52例.2例位于右上肢,占3.33%(2/60),1例位于双侧腋下,占1.67%(1/60).二维超声多表现为:淋巴结体积增大,形态多为椭圆形,包膜纤薄锐利、清晰,淋巴门结构多显示正常;皮质呈均质低回声.彩色多普勒超声表现:血流呈淋巴门型分布46例,占76.67%(46/60),边缘型血流9例,占15.00%(9/60),5例未见明显血流信号,占8.33%(5/60).结论:KFD病变淋巴结超声表现具有一定的特点,对临床诊断有一定的帮助.%Objective:To explore the value of ultrasonography in diagnosis of Kikuchi-Fujimoto disease (KFD) . Methods:Ultrasonic features of 60 cases with KFD confirmed by cystoscopy and pathology were analyzed retrospectively. Results : Of those 60 cases, 57 cases (95 ％) located in cervical lymph nodes,among which 54 cases involved in multiple areas.52 cases involved in the posterior cervical triangle, 2 cases (3. 33％) located in right upper extremity, one case (1. 67％)located in bilateral subaxillary lymph nodes. In gray-scale sonography images, most of the involved lymph nodes showed obvious envelope, acuminous border, disrinct and neat lymph hilar structure, homogeneous hypoechoic internal echo. In color Doppler images, 46 cases (76. 67％) showed hilar type, 9 cases (15. 00 ％) reveled peripheral type, 5 cases (8. 33 ％)didn ' t present any obvious vascularity. Conclusion : KFD has specific appearance in sonography and ultrasound plays an important role in diagnosis of KFD.
