The number of women undergoing breast implant procedures is increasing exponentially. It is, therefore, imperative for a radiologist to be familiar with the normal and abnormal imaging appearances of common breast implants. Diagnostic imaging studies such as mammography, ultrasonography, and magnetic resonance imaging are used to evaluate implant integrity, detect abnormalities of the implant and its surrounding capsule, and detect breast conditions unrelated to implants.

The case of a 36 year old woman who experienced a late, spontaneous breast seroma 5 years after augmentation in the absence of any known precipitating factors is reported. Although seroma is not an uncommon complication in the immediate postoperative period, it is extremely rare as a late complication of breast implantation. Magnetic resonance imaging is a reliable method to confirm the diagnosis of late seroma formation.
Repeated postaugmentation capsular formation following retromammary silicone implantation led surgeons to seek an alternative procedure. In Dempsey and Latham first reported the "subpectoral" route for location of the implant. Since then little data has been published comparing retromammary and retropectoral breast augmentation.
Elective cosmetic surgery, already popular in the United States, is on the rise. Breast augmentation is the most common cosmetic surgery performed in the United States, and it continues to increase. For radiologists who interpret either screening or diagnostic mammograms, an understanding of the diverse mammographic manifestations of breast augmentation can help produce a precise, accurate and relevant report that can help to provide optimal patient care.
The second position of breast implants is behind the pectoral muscle; this has been termed subpectoral or retropectoral. In women who have implants placed after mastectomy, the implant may be placed behind the pectoralis muscle. There are multiple options regarding the surgical access for placing the breast implant.
There are different types of breast implants, depending on the number of lumens and the type of filler. The most frequent ones are those with a silicone outer shell and one lumen filled with silicone gel or saline or double lumen silicone gel and saline, one inside the other. The saline filled implants have a valve in order to adjust the volume; this valve can be detected in images. The envelope is not visualized on mammography because of the high density of the silicone Fig.
