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 investigate the value of color Doppler ultrasound in the diagnosis of Kikuchi-Fujimoto disease (KFD). Methods: Two-dimensional and color Doppler sonographic findings of 60 KFD-affected lymph nodes confirmed by biopsy or surgical pathology were retrospectively analyzed. Results: Among the 60 patients, 57 cases were involved in cervical lymph node involvement, accounting for 95.00% (57/60), including 54 cases of multi-regional lesions and 52 cases of posterior cervical trigone. Two cases were located in the right upper extremity, accounting for 3.33% (2/60), and one was located in both armpits, accounting for 1.67% (1/60). Two-dimensional ultrasound showed more: the volume of lymph nodes increased, the shape of mostly oval, thin and slender capsule, clear, lymphatic structures showed normal; cortical homogeneous hypoechoic. Color Doppler ultrasound showed that there were 46 cases (76.67%) with marginal blood flow in 9 cases (15.00%, 9/60), 5 cases had no obvious blood flow signal , Accounting for 8.33% (5/60). Conclusion: The ultrasonographic features of lymph nodes in KFD lesions have certain characteristics and are helpful to clinical diagnosis.
