Silicone granuloma associated with peri-implant effusion and mild inflammation. (a) Axial short tau inversion recovery (STIR) sequence depicts hyperintense peri-implant effusion associated with a hypointense nodular component. (b) Axial T1 fat-saturated post-contrast sequence readily depicts the strong enhancement of the nodular component and the mild enhancement of the peri-implant effusion collection. This aspect could evocate a silicone granuloma; nevertheless, a core biopsy was performed to validate this diagnosis.
