【摘要】：目的探討超聲造影灌注缺損征象在可疑惡性頸部淋巴結(jié)中的應(yīng)用價(jià)值。方法納入可疑惡性頸部淋巴結(jié)156例(160個(gè)淋巴結(jié))行超聲造影,根據(jù)病理分為非結(jié)核性反應(yīng)性增生組、淋巴結(jié)結(jié)核組、轉(zhuǎn)移性淋巴結(jié)組及淋巴瘤組,比較四組淋巴結(jié)超聲造影增強(qiáng)及灌注模式、灌注缺損區(qū)特征。結(jié)果約51.9%(83/160)淋巴結(jié)超聲造影實(shí)質(zhì)相中存在灌注缺損,結(jié)核組(90.0%,11/47)及轉(zhuǎn)移組(73.8%,31/42)比例較多,非結(jié)核性反應(yīng)性增生組(23.4%,11/47)及淋巴瘤組(28.9%,11/38)比例較少,且56.7%(17/30)結(jié)核組灌注缺損區(qū)較大(灌注缺損區(qū)面積或整個(gè)淋巴結(jié)面積≥50%),其余三組灌注缺損較小。結(jié)論淋巴結(jié)超聲造影實(shí)質(zhì)相灌注缺損征象可見于良惡性病變,綜合動(dòng)脈相特征分析,可為可疑惡性頸部淋巴結(jié)鑒別診斷提供有價(jià)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，
