Figure 9a. M tuberculosis of the breast (diffuse type) in a 47-year-old woman with a 9-year history of systemic tuberculous disease. (a) Mammogram shows a diffuse lymphatic pattern, with thickening of the Cooper ligaments and superficial fascia. (b) Axillary mammogram demonstrates calcified nodes, a finding that is highly suggestive of tuberculosis in the appropriate clinical setting (as in this case).
