Which term is the MRI-based sign used to denote intracapsular rupture?

• A. Linguini sign - MRI
• B. Intra-capsular implant rupture
• C. Extra-capsular implant rupture
• D. Intracapsular implant rupture

Answer: (A)

Linguine sign on MRI indicates intracapsular rupture. When the implant shell tears but remains inside the fibrous capsule, the collapsed shell forms multiple curvilinear lines within the silicone gel that resemble strands of linguine. This distinct pattern is highly specific for rupture confined within the capsule, helping to distinguish intracapsular rupture from extracapsular rupture, where silicone leaks outside the capsule and may be seen in surrounding tissues. The term captures the characteristic appearance seen on silicone-specific MRI sequences, making it the best descriptor for this scenario. Other options either describe rupture location more generally or do not reference the MRI appearance itself, so they don’t convey the specific imaging sign as clearly.
