Which term describes rupture contained within the implant's capsule?

• A. Intra-capsular implant rupture
• B. Extra-capsular implant rupture
• C. Linguini sign - MRI
• D. Step ladder sign - US

Answer: (A)

When rupture is contained within the implant’s own fibrous capsule, it’s described as an intra-capsular implant rupture. In this situation the silicone gel has ruptured the implant shell but stays inside the surrounding capsule, so there isn’t silicone leaking into the surrounding breast tissue. On imaging, this pattern is recognized as the linguine sign on MRI, where collapsed strands of silicone appear inside the capsule, and on ultrasound as the step ladder sign, showing parallel, folded shell fragments within the capsule. If the rupture extended beyond the capsule into adjacent tissue, that would be an extra-capsular rupture.
