Abstract

Background

Osteoid osteoma typically presents with nocturnal pain relieved by NSAIDs. We report an atypical presentation in a 14-year-old male.

Case Presentation

Patient presented with progressive knee pain and limp. Imaging revealed a nidus in the proximal tibia. Radiofrequency ablation was performed with complete resolution of symptoms.

Conclusion

Unusual presentations of osteoid osteoma require a high index of suspicion. Minimally invasive treatment remains effective.

Introduction

Osteoid osteoma is a benign bone tumour accounting for approximately 10% of benign bone tumours. We present an unusual case with atypical clinical features.

Case Report

A 14-year-old male presented with 6 months of progressive right knee pain and antalgic gait. Plain radiographs were initially unremarkable. CT confirmed the nidus. Radiofrequency ablation was performed under CT guidance with successful outcome.

Discussion

This case highlights the importance of considering osteoid osteoma in the differential of paediatric knee pain, even when presentation is atypical.

Conclusion

Minimally invasive ablation provides excellent outcomes for osteoid osteoma with low morbidity.
