CT Findings of Axillary Tuberculosis Lymphadenitis: A Case Detected by Breast Cancer Screening Examination

Figure 1

Images from a 67-year-old woman with a left axillary mass. (a) Axillary US shows well-circumscribed markedly hypoechoic ovoid lymph nodes. Every node lacks a hilum. Note the multiple rough calcifications (arrows) within the lymph node. (b) Axillary tail mammographic films show irregularly shaped macrocalcifications and matted, slightly dense homogeneous lymph nodes (arrows). Screening mammographic films show normal findings (not shown). (c) Coronal CT image after administration of intravenous contrast shows the presence of multiple well-circumscribed lymph nodes spread throughout the axillary vein (long dotted line) and dorsal thoracic vein (dotted line) in the left axilla and supraclavicular (arrowhead) and infraclavicular regions. Most nodes have large and dotted calcifications. Arrow indicates axillary artery. (d) Sagittal CT image shows the largest node, which has no calcification itself but is surrounded by nodules rich in calcification. Arrows indicate dorsal thoracic vein. (e) Axial CT image shows the lymph nodes are distributed extending from the axilla to the infraclavicular region around the axillary vein (arrow). (f) Chest radiograph shows clustered calcifications in the left deep lower axilla (arrows).
