OSTEOID OSTEOMA OF THE CORACOID PROCESS: CASE REPORT WITH LITERATURE REVIEW
Keywords:Osteoma, osteoid; Scapula – pathology; Shoulder joint – pathology; Pain – therapy; Case reports
Osteoid osteoma (OO) is the most common benign osteogenic bone tumor that predominantly affects young adults. OO is commonly localized in long bones, and therefore, it is rarely considered in differential diagnosis of chronic shoulder pain. We report a case of a 22-year-old male athlete, without history of previous trauma, who presented to our Department with chronic shoulder pain, which escalated during the night and responded to nonsteroidal anti-infl ammatory drug treatment. Considering these typical symptoms, the diagnostic pathway was immediately directed towards OO, with magnetic resonance and computed tomography confirming the diagnosis of OO of the coracoid process (CP). Since neurovascular structures are in the proximity of CP, and this very delicate area does not support radiofrequency ablation, we decided to perform an open procedure with drilling of the lesion and excochleation. The pain withdrew immediately after the procedure, and on six-month follow up the patient remained pain free. In the treatment of OO of the CP, we recommend open surgical procedure with tumor ablation by drilling instead of CP resection, presenting a safe, simple and low-cost method that simultaneously completely destroys the lesion and preserves the anatomical and functional role of CP.
