Ultrasound (US) and US‐guided fine‐needle aspiration biopsy (FNA) were performed in 91 nonpalpable neck nodes of 70 patients, 93% 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. © 1997 John Wiley & Sons, Inc. J Clin Ultrasound 25:283–292, 1997
