Case in brief
A 34-year-old woman presented with progressive gluteal pain and swelling due to a giant cell tumor of the bone involving the sacroiliac joint. Imaging revealed an osteolytic lesion with soft-tissue involvement. Preoperative treatment with denosumab facilitated tumor resection and spinopelvic reconstruction. The patient had an uneventful recovery, with stable follow-up imaging showing no recurrence.
Diagnostic / clinical pearl
Preoperative denosumab can enhance surgical outcomes in giant cell tumors of the bone by promoting ossification and reducing intraoperative blood loss.
Why it matters
This case highlights the importance of careful surgical planning and the potential role of denosumab in managing complex bone tumors near critical structures.
