Incidental finding on a routine CT thorax.

Implant ruptures can be subdivided into intra and extra capsular. CT is not a modality of choice for diagnosing a rupture and breast MRI is preferred. 

In the case of a ruptured saline implant, only the capsule remains after the saline is absorbed by the body. In case of a silicone implant rupture, this remains in the soft tissue, the small amounts that do get taken up in lymphatics tend to drain to the axillary lymph nodes causing enlargement or calcification.
