Pregnancy Complication Caused by Migrated Injectable Breast Filler: A Case Report

Background: Minimally invasive cosmetic procedures, including soft tissue filler injections, are increasingly performed worldwide. While complications such as inflammation, migration, and granuloma formation have been reported, pregnancy-related complications resulting from dermal filler migration have not yet been documented. Case: We describe the first known case of a 45-year-old primigravida with extensive breast filler migration, originally injected 17 years before conception, that extended to the lower abdomen and complicated both prenatal ultrasound evaluation and cesarean delivery. By 36 weeks of gestation, the migration had extended to the vulvar region. At 36 weeks and 2 days, an elective cesarean section was performed. Pelvic magnetic resonance imaging (MRI) and intraoperative findings demonstrated filler deposits between the subcutaneous tissue and the fascial layer, which restricted fascial mobility and hindered fetal extraction. Although additional fascial incisions were required to facilitate delivery, the neonate experienced no postnatal complications, and the maternal postoperative course was uneventful. Conclusions: This case highlights the importance of thorough cosmetic history-taking in pregnant women and emphasizes the need for clinical awareness and guidelines that address the long-term obstetric implications of dermal filler migration.
