Can a capsule left in the body cause problems later?
A thin healthy capsule usually collapses quietly, but retained capsules occasionally cause late seroma, calcification that complicates imaging, or small silicone granulomas.
When a healthy capsule is left at explant, the usual story is quiet: the walls collapse against each other and the body absorbs the thin scar layer over time. Knowing the exceptions helps patients watch for the right things.
The uncommon ways a retained capsule shows up
Three scenarios account for most late issues. Fluid can accumulate between capsule walls that failed to seal, producing a late seroma that presents as new swelling. Calcification within an old capsule can appear on later mammograms and needs context to be read correctly. And when a silicone rupture preceded the explant, residual gel held by a retained capsule can form small granulomas. Each is uncommon, and each is manageable when identified.
The practical safeguards are simple: keep the operative note stating whether and how much capsule stayed, mention it at every breast imaging visit, and have new swelling, firmness, or a lump examined rather than watched. Whether leaving the capsule was the right call varies with each patient’s original tissue findings — if you are unsure what stayed behind in your own surgery, a records review at a consultation settles it.
