Ultrasound (US) and US-guided fine-needle aspiration biopsy (FNA) were performed in 91 nonpalpable neck nodes of 70 patients, 98% of which had known malignancy. Various sonographic findings were evaluated for predicting malignancy. The accuracy of US-guided FNA for detecting malignancy was 88%, with 96% sensitivity and 94% specificity. The ratio of minimal to maximal axial diameters of a node was most valid for predicting malignancy with US. A ratio of more than 0.55 yielded the highest accuracy (80%) (92% sensitivity, 63% specificity). Addition of any other factors to this criterion did not improve its accuracy. US and US-guided FNA are accurate for the assessment of nonpalpable neck nodes. Lymph nodes with a round configuration should be biopsied in patients with known malignancy.
对70例患者的91个不可触及的颈部淋巴结进行了超声（US）检查及超声引导下细针穿刺活检（FNA），其中98%的患者已知患有恶性肿瘤。对各种超声检查结果进行评估以预测恶性肿瘤。超声引导下FNA检测恶性肿瘤的准确率为88%，敏感性为96%，特异性为94%。淋巴结最小与最大轴向直径之比对超声预测恶性肿瘤最为有效。该比值大于0.55时准确率最高（80%）（敏感性92%，特异性63%）。在此标准中加入任何其他因素都不能提高其准确率。超声及超声引导下FNA对不可触及的颈部淋巴结评估准确。已知患有恶性肿瘤的患者中，圆形的淋巴结应进行活检。
