Gluteal augmentation with autologous fat grafting is an increasingly popular procedure. While complication rates are low, the clinical and imaging evaluation of the various complications can be challenging. We report a case of distal migration of a failed gluteal fat graft in a young female patient presenting as a soft tissue mass in the knee, mimicking a soft tissue sarcoma. Surgical resection of the migrated fat graft confirmed the diagnosis. The diagnosis was challenging as the patient was initially reluctant to disclose her surgical history due to perceived negative social stigmas related to cosmetic contouring procedures. This case highlights the imaging findings of a rare complication following autologous fat grafting for gluteal augmentation and the importance of obtaining a thorough medical history.
自体脂肪移植丰臀术是一种越来越受欢迎的手术。虽然并发症发生率较低，但对各种并发症的临床和影像学评估具有一定挑战性。我们报告了一例年轻女性患者因臀部脂肪移植失败导致移植物远端迁移，在膝关节形成软组织肿块，类似于软组织肉瘤。手术切除移植物证实了该诊断。该病例的诊断具有一定挑战性，因为患者最初因担心与美容塑形手术相关的负面社会耻辱感而不愿透露其手术史。本病例强调了自体脂肪移植丰臀术后罕见并发症的影像学表现，以及获取详细病史的重要性。
