Saline Breast Implant Calcification

Saline Breast Implant Calcification

General Considerations

• Calcification can occur in the fibrous capsule that develops around a breast implant
• More commonly occurs with first generation silicone implants, when the implant has been present for more than a decade, rupture of the implant
• Subglandular implants are more likely to calcify than submuscular implants

Clinical Findings

• Calcifications are considered of no clinical significance unless they mimic or obscure calcifications of malignancy on mammograms
• Implants are ovoid in shape initially but may become rounder with calcification
• May produce firmness
• May produce pain

Imaging Findings

• Calcification may be focal or diffuse
• Thin-rim of calcification that outlines implant
• Does not imply rupture
• MRI is the most accurate imaging examination for the evaluation of silicone breast implant rupture

Treatment

• None required for the calcification itself 

Calcified Breast Implant. Thin, curvilinear calcification (white arrows) surrounds the capsule of this patient's right saline breast implant done inserted 12 years earlier. The left implant is denser than normal breast tissue (yellow arrow), but its calcification is not visible on this chest radiograph.
