title: Diagnosis of ruptured breast implants through high-resolution ultrasound combined with real-time elastography.
abstract: BACKGROUND
  Implant rupture as a late complication of breast implant surgery is often a silent phenomenon that is difficult to diagnose. Sonoelastography is a new ultrasound-based technique that allows assessment of tissue elasticity.
  
  
  OBJECTIVE
  This study was undertaken to evaluate elastographic findings in normal and ruptured breast implants.
  
  
  METHODS
  This prospective study included 28 implants in 16 patients, all of whom underwent high-resolution ultrasound and real-time elastography. The diagnosis of implant rupture was confirmed by surgery.
  
  
  RESULTS
  Implant rupture was diagnosed in 5 out of 28 implants (17.9%). In those patients with ruptured implants, 3 had no symptoms, 1 presented with pain, and 1 complained of ipsilateral axillary lymph node swelling. Implants with a homogenous anechoic interior were considered to be intact. Ultrasound findings indicating implant rupture included multiple parallel echogenic lines in the implant interior in 2 cases and a mix of hyperechoic and hypoechoic masses in 3 cases. The feasibility of real-time elastography of implants was demonstrated in all cases. Elastograms of intact implants revealed a typical blue-green-red pattern familiar from cystic lesions. In all 5 ruptured implants, elastography revealed yellow-green figures without typical layering.
  
  
  CONCLUSIONS
  To the authors' knowledge this is the first series to combine high-resolution ultrasound with real-time elastography for the diagnosis of implant rupture. Since there are distinct differences between elastograms of intact and ruptured implants, addition of real-time elastography to conventional ultrasound may improve implant surveillance and obviate the need for magnetic resonance imaging.
