Which finding is consistent with an intact silicone implant on ultrasound?

• A. Intact Implant With Smooth Contours And No Peri-Implant Fluid
• B. Irregular Shell With Peri-Implant Fluid Or Mass
• C. Posterior Acoustic Shadowing Behind An Implant
• D. Calcified Surrounding Tissue

Answer: (A)

An intact silicone implant on ultrasound is seen as a smooth, continuous implant shell with regular contours and no fluid around the implant. This combination—smooth, well-defined margins and absence of peri-implant fluid or a mass—indicates the implant has not ruptured and the surrounding capsule is stable.

If you saw an irregular shell with peri-implant fluid or a mass, that would point toward rupture or complication, not intact status. Posterior acoustic shadowing behind the implant can occur as a normal artifact and doesn’t by itself indicate whether the implant is intact. Calcified surrounding tissue may reflect prior surgery or chronic changes but doesn’t specifically confirm an intact implant.
