Case Discussion

A BI-RADS 4 lesion under the breast imaging-reporting and data system refers to a suspicious abnormality. BI-RADS 4 lesions may not have the characteristic morphology of breast cancer but have a definite probability of being malignant. A biopsy is recommended for these lesions.

The patient underwent ultrasound guided core needle biopsy, and histopathologic evaluation confirms invasive ductal carcinoma.
