Tumours of the odontoid peg revisited

Abstract

Introduction: Tumours of the odontoid peg are rare but can potentially cause significant morbidity and mortality. Methods: A retrospective review of oncology and radiology database of tertiary orthopaedic oncology centre for all lesions affecting the odontoid peg over the last 12 years was performed. Results: We identified a total of 15 tumours involving the odontoid peg, majority being malignant. Myeloma was the most common tumour. Conclusion: Tumours of the odontoid peg are rare. Spinal surgeons and Radiologists need to be aware of them.
