ABSTRACT
Invasive lobular carcinoma is the second most common breast malignancy. Mammographic finding of invasive lobular carcinoma is often subtle or negative due to its histological feature showing infiltration of tumor cells into surrounding tissue with scanty fibrotic reaction. Thus, ultrasound plays an important role in detection of invasive lobular carcinoma. We report here on our experience with a 70-year-old female who had invasive lobular carcinoma of the breast with unique ultrasound findings; a mixed hyper- and hypoechoic mass at the fatty layer mimicking fat necrosis.
