【摘要】：目的探讨超声造影灌注缺损征象在可疑恶性颈部淋巴结中的应用价值。方法纳入可疑恶性颈部淋巴结156例(160个淋巴结)行超声造影,根据病理分为非结核性反应性增生组、淋巴结结核组、转移性淋巴结组及淋巴瘤组,比较四组淋巴结超声造影增强及灌注模式、灌注缺损区特征。结果约51.9%(83/160)淋巴结超声造影实质相中存在灌注缺损,结核组(90.0%,11/47)及转移组(73.8%,31/42)比例较多,非结核性反应性增生组(23.4%,11/47)及淋巴瘤组(28.9%,11/38)比例较少,且56.7%(17/30)结核组灌注缺损区较大(灌注缺损区面积或整个淋巴结面积≥50%),其余三组灌注缺损较小。结论淋巴结超声造影实质相灌注缺损征象可见于良恶性病变,综合动脉相特征分析,可为可疑恶性颈部淋巴结鉴别诊断提供有价值的信息。
[Abstract]:Objective to evaluate the value of perfusion defect in suspected malignant cervical lymph nodes. Methods 156 patients (160 lymph nodes) with suspected malignant cervical lymph nodes were divided into non-tuberculous reactive hyperplasia group according to pathology. In lymph node tuberculosis group, metastatic lymph node group and lymphoma group, the enhancement and perfusion patterns and the characteristics of perfusion defect were compared among the four groups. Results there was a perfusion defect in the parenchyma of lymph node sonography. In the tuberculosis group (90.010 / 47) and the metastatic group (73.810 / 41 / 42), the proportion of the non-tuberculous reactive hyperplasia group was 23.4 / 47) and the proportion of the lymphoma group was 28.910 / 38). In the tuberculosis group, the perfusion defect area was larger (the perfusion defect area or the whole lymph node area 鈮，
