Radiologic Findings of Various Diseases of the Axillary Lymph Node with Pathologic Correlations

Axillary lymphadenopathy has multiple variable pathologic conditions such as a malignant or benign condition. It is important that we determine the radiologic findings of malignant lymphadenopathy and in turn determine the further course of evaluation for the lesion, because metastatic axillary lymphadenopathy represents an important prognostic factor. Recently, an ultrasonographic-guided axillary lymph node biopsy has been widely used as a diagnostic tool. We discuss the radiologic and pathologic findings of variable axilla diseases and outline the specific findings for determining the results of a lymph node biopsy.
