Osteoid osteoma is a benign bone tumor commonly affecting young adults, characterized by severe nocturnal pain relieved by nonsteroidal anti-inflammatory drugs. Computed tomography (CT)-guided radiofrequency ablation (RFA) has emerged as a minimally invasive and highly effective alternative to surgical excision. We report the case of a 20-year-old patient presenting with progressive thigh pain. CT imaging revealed a 10 mm cortical nidus in the femoral metaphysis. The patient underwent CT-guided RFA under spinal anesthesia, achieving complete nidus ablation with immediate pain relief and no complications. RFA induces localized thermal coagulation, ensuring precise nidus destruction while preserving surrounding bone integrity. Clinical success rates exceed 90%, with rapid recovery and minimal recurrence. This case highlights CT-guided RFA as the treatment of choice for osteoid osteoma, combining safety, efficacy, and cost-effectiveness.
