Post-operative imaging surveillance of breast cancer patients status post lumpectomy with BioZorb implant placement.

The evolving nature of newer surgical techniques and devices adds to the challenge of interpreting breast imaging in the post lumpectomy setting. The BioZorb surgical marker placed at lumpectomy sites for post-operative radiation targeting has its own distinct imaging appearance on each modality. Determining the expected follow-up imaging findings unique to this relatively new device is an ongoing endeavor with minimal literature on this topic. The following series of cases of post BioZorb breast surveillance are one of the first reported in the literature to provide examples of developing asymmetries and new or enlarging masses adjacent to the BioZorb site along with the final pathologic diagnosis for each case. Pathology findings range from fat necrosis and foreign body reaction to recurrent disease.
