IntroductionOsteoid osteoma (OO) is a benign osteoblastic lesion that occurs primarily in young men and accounts for approximately 11% of all benign bone tumors (1). Almost 80% of all “OO” are detected in patients younger than 30 years old. These lesions are generally seen in the shaft of the long bones, especially the femur or tibia, in the lower limb. They are only rarely detected in the flat bones (2-5). “OO” includes a well-defined osteoblastic mass, known as a nidus, which is surrounded by the reactive bone sclerosis zone. Following nidus excision, the sclerosis zone gradually disappears, indicating a secondary, reversible alteration (6). Patients with OOs typically report generalized pain at the site of their benign tumors, and their pain can be more severe and frequent at night. Non-steroidal anti-inflammatory drugs (NSAID) and salicylates are commonly used to manage the pain (7).It is extremely rare for OO to occur in the scapula, especially the coracoid process (CP), therefore it is not commonly recognized as a differential diagnosis in young people with shoulder pain (8). Various therapeutic approaches have been proposed for treating these lesions, including complete surgical excision and percutaneous radiofrequency ablation (RFA) (9). Nevertheless, it is critical to note that the use of any of these treatment strategies may lead to permanent impairment of the articular cartilage or physics in younger patients (10). Herein, we present the first case of OO of the base of CP, treated successfully with RFA in the literature.
