Radiographic evidence of breast implant rupture

A patient with a past history of breast augmentation, fibrous capsule formation, and repeated closed capsulotomies is described. Deformity of the breast occurred in conjunction with radiographic evidence of implant rupture. This rupture was confirmed at the time of open capsulotomy and implant exchange. After augmentation and closed capsulotomy, a diverticulum of the fibrous breast capsule can mimic implant rupture on mammography despite an intact prosthesis. Mammographic features, including multiple loculations and streaming of implant contents, increase the suspicion of rupture.
