Digital Breast Tomosynthesis Findings after Surgical Lipomodeling in a Breast Cancer Survivor

Abstract

Autologous fat grafting or lipomodeling is a newly-adopted technique that is gaining increasing popularity in the treatment of contour deformities following breast conservation therapy. Here, we describe the case of a 47-year-old woman with a prior history of breast cancer treated with a lumpectomy and radiation therapy. She underwent lipomodeling not only of her treated breast but also of the contralateral breast. She presented for her annual mammogram which was performed with digital breast tomosynthesis. On imaging, a space-occupying lesion of mixed density was seen, expanding the lumpectomy site. There was also subtle distortion in the contralateral, non-treated breast. This case aims to highlight the mammographic and tomosynthesis findings seen following lipomodeling that may present diagnostic challenges in this patient population.
