Management of the Isolated Abnormal Axillary Lymph Node: From Uncertainty to Action

An isolated abnormal axillary lymph node on imaging carries a malignancy risk of up to 33%, most commonly lymphoma, breast cancer, or metastases. Radiologists can guide management through patient history, sonographic features, and recommending targeted tissue sampling.

• Design: Narrative review of imaging and management of the isolated abnormal axillary lymph node, synthesizing evidence from multiple studies.
• Key finding: Review maps sonographic cortical morphology and vascular patterns to malignancy risk categories and outlines a stepwise diagnostic algorithm, though exact sensitivity/specificity figures are not reported in source.
• Limitation: As a review, it is limited to the quality of the underlying primary studies and does not provide new prospective validation data.
