Objective  To explore the diagnostic value of contrast-enhanced ultrasonography (CEUS) in axillary and internal mammary lymph node metastasis of invasive breast cancer. Methods  A total of 100 patients with invasive breast cancer treated from September 2020 to September 2022 were selected. Preoperative CEUS examination was completed, and the perfusion sequence, enhancement mode and enhancement sequence of lymph nodes were dynamically observed. The CEUS characteristics of metastatic and benign lymph nodes were compared. Using postoperative pathological results as the gold standard, the diagnostic efficacy of CEUS in evaluating lymph node status was analyzed. Results  Among the 100 patients, 28 patients were diagnosed with metastatic axillary lymph nodes (ALN) by pathological biopsy. The sensitivity, specificity, accuracy, positive prediction rate and negative prediction rate of CEUS in evaluating ALN status were 71.4%, 87.5%, 83.0%, 69.0% and 88.7%, respectively. In 9 patients, CEUS showed internal mammary lymph node metastasis, and postoperative pathological examination confirmed that 5 patients had internal mammary lymph node metastasis, so the positive predictive rate of CEUS was 55.6%. Conclusion  CEUS can evaluate the metastatic status of axillary and internal mammary lymph nodes.
