Osteoid osteoma (OO) is a primary benign bone tumor first described by Jaffe in 1935 [1]. It accounts for approximately 12% of benign bone tumors and primarily affects young people, with a marked male predominance [2]. Clinically, it manifests as intense nocturnal pain, typically relieved by nonsteroidal anti- inflammatory drugs (NSAIDs) [3]. Imaging plays a central role in positive and topographic diagnosis, with computed tomography (CT) being the reference examination for identifying the nidus [4]. Treatment has evolved from conventional surgery to minimally invasive percutaneous techniques, including radiofrequency ablation and cryoablation [5,6]. We report two cases of osteoid osteomas treated percutaneously, highlighting the diagnostic contribution of imaging and the effectiveness of modern techniques.
