Galactorrhea and galactoceles are relatively uncommon complications after breast augmentation surgery, but should be considered in the differential of an enlarged breast. We present a case of a 34-year-old woman who had a remote history of bilateral breast augmentation and developed a unilateral galactocele while breast-feeding. She subsequently underwent an incision and drainage, as well as medical management with bromocriptine. Her galactocele resolved adequately with this treatment. Surgeons performing breast augmentation should be aware of the clinical presentation as well as the treatment options for this entity.
