[False-negative cases of axillary ultrasonography: how much size?].
OBJECTIVE
1. To review the sonographic criteria of axillary lymph node status in breast cancer patients. 2. To understand imaging pathologic correlations that the false-negative cases of axillary ultrasonography.
The sonographic criteria, the accuracy of sonographic axillary ultrasonography, imaging pathologic correlations in false-negative cases, measurement of largest malignant focus size in lymph node, classification of ratio of malignant focus size, ratio of micro metastasis.


CONCLUSIONS
1. Recently, lymph node evaluation that using serial section and immunohistochemical stains makes it difficult to detect imaging modalities. 2. Ultrasonography is limited how to detect the example of sentinel lymph node biopsy non-indications.
