MRI DIAGNOSIS OF RUPTURED SILICONE

Posted On: May 11, 2012 Author: Dr. Stuart Linder Posted In: Breast topics, Home, Ruptured Implant

Patients who present with silicone gel implants may present with ruptured silicone implants, although it is difficult to detect clinically.  Patients should undergo every two to three years postaugmentation or augmentation revision with silicone implants and MRI in order to determine the integrity of its shell or the bags.  Our patients are instructed that the MRIs are extremely important with silicone implants in that they allow the radiologist and the surgeon to determine a rupture intra- versus extracapsular.  The intracapsular rupture of silicone implants can be detected by what is called the Linguine sign.  The weightiness and black and white echo seen on the MRI is pathognomonic for the ruptured silicone bag.

The next four pictures represent a ruptured silicone on the right.  Notice the Linguine sign as well as the medial rupture of the implant on the right implant.  The left implant is completely intact.  There is no evidence of loss of integrity of the shell or Linguine sign.  The implants that rupture in silicone patients are referred to as “silent ruptures.”  This is different from saline implants that are referred to as “clinical ruptures” which can be diagnosed by visualization of the breast, showing an obvious asymmetry.  Remember that mammograms and ultrasounds can provide false positive or actually more often false negative results, indicating that the silicone implants are intact, but they are actually ruptured.
