This study was performed to determine the importance of contrast-enhanced sonography for axillary lymph node metastatic breast cancer. Contrast-enhanced sonographic findings in 5 patients with breast cancer and axillary lymph node metastasis are discussed, and imaging-pathologic correlations are also presented in 3 cases. In all 5 cases, lymph nodes showed a perfusion defect in the late phase. Rapid arterial enhancement and wash-out were observed in 2 cases in which we performed second injections. Contrast-enhanced sonography may be effective for identifying metastatic lesions in lymph nodes, especially in the early stages.
