Fig. 5From: Mammographically occult breast cancers detected with AI-based diagnosis supporting software: clinical and histopathologic characteristicsA 48-year-old woman with invasive ductal carcinoma in the right breast. a A BB marker was attached at the right axilla, where an enlarged lymph node was noted. However, no abnormal finding was detected in both breasts by a radiologist. b–d AI highlighted a focal area in the mid-portion of the right breast, which correlated with the location of the cancer in US and MRI. The malignancy score of the cancer was 44.8. Histopathologic examination of core needle biopsy showed a high histologic grade invasive ductal carcinoma that was estrogen receptor-negative, progesterone receptor-negative, and human epidermal growth factor receptor-2-negative. Right breast-conserving operation was performed after neoadjuvant chemotherapy, and no residual invasive ductal carcinoma was foundBack to article page
