Denosumab therapy was initiated to reduce tumour vascularity and facilitate resection. After preoperative embolisation of the left VA, total en bloc resection of the tumour was performed. Postoperatively, the patient experienced transient left upper extremity weakness, which improved significantly over time. Follow-up imaging showed successful bony fusion and no recurrence. This case highlights the importance of multidisciplinary planning in managing cervical spine GCTs involving critical neurovascular structures. Combined denosumab therapy and VA embolisation can enable safe and complete tumour resection, potentially improving outcomes and reducing recurrence risk, especially in young patients.<\/jats:p>","DOI":"10.1136\/bcr-2025-269499","type":"journal-article","created":{"date-parts":[[2026,9,8]],"date-time":"2026-09-08T11:55:18Z","timestamp":1788868518000},"page":"e269499","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Total
