Accidental injection of autologous fat into the breast implant: a case report highlighting radiological findings

Autologous fat grafting is a popular technique for breast augmentation and improving breast contour depressions. It is a technique that involves using the patient's own adipose tissue to be applied on a subcutaneous area to increase total fat volume. Intraimplant fat is an unexpected finding after autologous fat grafting. A 51-year-old asymptomatic female who underwent breast augmentation with silicone implants and secondary breast augmentation with autologous fat grafting presented with unidentified cluster of radiolucencies superimposed to left implant on screening mammogram. Corresponding MRI revealed intraimplant fat intensities. This case represents a previously unreported intraimplant injection of fat with resultant intracapsular rupture and highlights the radiological findings of intracapsular implant rupture.
